Han, Yu;Jiao, Nianzhi;Zhang, Yao;Zhang, Fan;He, Chen;Liang, Xuejiao;Cai, Ruanhong;Shi, Quan;Tang, Kai research published 《 Opportunistic bacteria with reduced genomes are effective competitors for organic nitrogen compounds in coastal dinoflagellate blooms》, the research content is summarized as follows. Phytoplankton blooms are frequent events in coastal areas and increase the production of organic matter that initially shapes the growth of opportunistic heterotrophic bacteria. However, it is unclear how these opportunists are involved in the transformation of dissolved organic matter (DOM) when blooms occur and the subsequent impacts on biogeochem. cycles. We used a combination of genomic, proteomic, and metabolomic approaches to study bacterial diversity, genome traits, and metabolic responses to assess the source and lability of DOM in a spring coastal bloom of Akashiwo sanguinea. We identified mols. that significantly increased during bloom development, predominantly belonging to amino acids, dipeptides, lipids, nucleotides, and nucleosides. The opportunistic members of the bacterial genera Polaribacter, Lentibacter, and Litoricola represented a significant proportion of the free-living and particle-associated bacterial assemblages during the stationary phase of the bloom. Polaribacter marinivivus, Lentibacter algarum, and Litoricola marina were isolated and their genomes exhibited streamlining characterized by small genome size and low GC content and non-coding densities, as well as a smaller number of transporters and peptidases compared to closely related species. However, the core proteomes identified house-keeping functions, such as various substrate transporters, peptidases, motility, chemotaxis, and antioxidants, in response to bloom-derived DOM. We observed a unique metabolic signature for the three species in the utilization of multiple dissolved organic nitrogen compounds The metabolomic data showed that amino acids and dipeptides (such as isoleucine and proline) were preferentially taken up by P. marinivivus and L. algarum, whereas nucleotides and nucleosides (such as adenosine and purine) were preferentially selected by L. marina. The results suggest that the enriched DOM in stationary phase of phytoplankton bloom is a result of ammonium depletion. This environment drives genomic streamlining of opportunistic bacteria to exploit their preferred nitrogen-containing compounds and maintain nutrient cycling.

Halder, Moumita;Bhatia, Yatin;Singh, Yashveer research published 《 Self-assembled di- and tripeptide gels for the passive entrapment and pH-responsive, sustained release of an antidiabetic drug, glimepiride》, the research content is summarized as follows. Diabetes is a global epidemic that poses a severe challenge to public health. The characteristic features of this disease are hyperglycemia and deterioration of the function of pancreatic β-cells, which leads to oxidative stress and organ damage. Glimepiride is used to treat type II diabetes but is associated with side effects, like lower half-life, faster elimination, and hypoglycemia. Self-assembled peptide gels have drawn attention as a drug delivery depot because of their biocompatibility, diverse design, tunable functionality, and dynamic self-assembly properties. In order to overcome the challenge of oxidative stress and side effects associated with the use of glimepiride, we have developed glimepiride-loaded, self-assembled peptide gels from di- and tripeptides employing amino acids with inherent antioxidant properties. Dipeptides, Fmoc-Tyr-Tyr-NH₂ (YY) and Fmoc-Trp-Trp-NH₂ (WW), and a tripeptide, Fmoc-Trp-Trp-His-NH₂ (WWH), were developed and self-assembled into gels. The gels exhibited excellent viscoelastic properties and self-healing abilities, and the presence of β-sheet secondary structures. The dipeptide gels provided a sustained drug release but more drug was released at physiol. pH (7.4) than acidic pH (5 and 6), whereas the tripeptide gel released more drug at acidic pH. The gels showed free radical scavenging activities of more than 90% and were able to decrease the amount of oxidative stress caused by the ROS in HepG2 cells. They were non-toxic to the cell line tested and HepG2 cells treated with the releasate of tripeptide gels showed enhanced glucose uptake. This work for the first time reports the development of glimepiride-loaded self-assembled peptide gels, which can serve as a dynamic, multidimensional biomaterial to reduce oxidative stress, hypoglycemia, and repetitive dosing of drugs in diabetic patients by controlling glimepiride release.

Increasing grain yield has always been the primary goal of crop breeding. KLUH/CYP78A5 has been shown to affect seed size in several plant species, but the relevant mol. mechanism is still unclear and there are no reports of this gene contributing to yield. Here, we demonstrate that modified expression of TaCYP78A5 can enhance wheat grain weight and grain yield per plant by accumulating auxin. TaCYP78A5 is highly expressed in maternal tissues, including ovary and seed coat during wheat development. The constitutive overexpression of TaCYP78A5 leads to significantly increased seed size and weight but not grain yield per plant due to the strengthening of apical dominance. However, localized overexpression of TaCYP78A5 in maternal integument enhances grain weight and grain yield per plant by 4.3%-18.8% and 9.6%-14.7%, resp., in field trials. Transcriptome and hormone metabolome analyses reveal that TaCYP78A5 participates in auxin synthesis pathway and promotes auxin accumulation and cell wall remodelling in ovary. Phenotype investigation and cytol. observation show that localized overexpression of TaCYP78A5 in ovary results in delayed flowering and prolonged proliferation of maternal integument cells, which promote grain enlargement. Moreover, naturally occurring variations in the promoter of TaCYP78A5-2A contribute to thousand-grain weight (TGW) and grain yield per plant of wheat;TaCYP78A5-2A haplotype Ap-HapII with higher activity is favorable for improving grain weight and grain yield per plant and has been pos. selected in wheat breeding. Then, a functional marker of TaCYP78A5 haplotype Ap-HapII is developed for marker-assisted selection in wheat grain and yield improvement.

Acetamiprid is a neonicotinoid insecticide used worldwide that has caused environmental pollution and adverse effects on ecosystems. Here, a novel bacterium, Pseudaminobacter salicylatoxidans CGMCC 1.17248, was isolated to rapidly degrade acetamiprid to IM-1-2 via hydration. Gene cloning and overexpression demonstrated that two nitrile hydratases, AnhA and AnhB, converted acetamiprid to IM-1-2. Escherichia coli overexpressing AnhA and AnhB degraded 98.1% and 94.0% of acetamiprid (1.0 mmol L^-1) in 5 min and 8 h, resp. The pure AnhA and AnhB had a V_max value of 14.12 and 1.20 μmol mg^-1 min^-1, resp., and a Km value of 1.02 mmol L^-1 and 2.95 mmol L^-1, resp. Compared with AnhA, AnhB had broad pH stability, as well as metal ions and organic solvents tolerance. Expression of AnhA and AnhB was induced by decreasing the nutrient concentration of culture broth and addition of urea and therefore significantly enhanced acetamiprid degradation of CGMCC 1.17248. qPCR indicated that the expression of AnhA and AnhB under the cultured conditions of 1/15 lysogeny broth or 0.5% urea addition was improved by from 2.2 to 5.3 times. The results presented herein will facilitate development of bioremediation agents for acetamiprid pollution and understanding of the functional role of bacterial nitrile hydratase.

The emergence of multidrug-resistant bacteria has major issues for treating bacterial pneumonia. Currently, anoplin (GLLKRIKTLL-NH₂) is a natural antimicrobial candidate derived from wasp venom. In this study, a series of new antimicrobial peptide (AMP) anoplin analogs were designed and synthesized. The relationship between their biol. activities and their pos. charge, hydrophobicity, amphipathicity, and secondary structure are described. The characteristic shared by these peptides is that pos. charged amino acids and hydrophobic amino acids are severally arranged on the hydrophilic and hydrophobic surface of the α-helix to form a completely amphiphilic structure. To achieve ideal AMPs, below the range of the threshold of the cytotoxicity and hemolytic activity, their charges and hydrophobicity were increased as much. Among the new analogs, A-21 (KWWKKWKKWW-NH₂) exhibited the greatest antimicrobial activity (geometric mean of min. inhibitory concentrations = 4.76μM) against all the tested bacterial strains, high bacterial cell selectivity in vitro, high effectiveness against bacterial pneumonia in mice infected with Klebsiella pneumoniae, and low toxicity in mice (LD₅₀ = 82.01 mg/kg). A-21 exhibited a potent bacterial membrane-damaging mechanism and lipopolysaccharide-binding ability. These data provide evidence that A-21 is a promising antimicrobial candidate for the treatment of bacterial pneumonia.

Fmoc-L-Trp-OH is synthesized by reacting Naphthalene with glycine, followed by hydrolysis of the ester group under trifluoroacetic acid. The product is then conjugated with a polypeptide. This method of synthesis was developed as a way to produce peptides that are difficult to synthesize using solid-phase chemistry., 35737-15-6.

The bioisosteric substitutions of the piperazine ring were explored with a series of aminopiperidines and piperidine amines wherein compounds with either a terminal tertiary amine or amide were synthesized. Several lead compounds showed high to moderate DAT affinities and metabolic stability in rat liver microsomes. N-(2-((bis(4-fluorophenyl)methyl)sulfinyl)ethyl)-1-(4-fluorobenzyl)piperidin-4-amine (DAT K_i = 50.6 nM), I [R= F] (DAT K_i = 77.2 nM) and II [X₁=X₂= F] (DAT K_i = 30.0 nM) produced only minimal stimulation of ambulatory activity in mice, compared to cocaine, suggesting an atypical DAT inhibitor profile.
