post-translationally modified frog skin-derived antimicrobial peptides are effective against aeromonas sobria.antimicrobial peptides (brevinin1 hyba1 and brevinin1 hyba2) identified from the skin secretion of an endemic frog species of western ghats were studied against fish pathogens. post-translational modifications such as c-terminal amidation and cyclization of the peptides were enhanced on the activity against aeromonas sobria. based on the minimum inhibitory concentration (3 μm), cyclic amidated brevinin hyba2 was identified as the most promising antimicrobial agent against a. sobria and can be de ...201728153544
strong genomic and phenotypic heterogeneity in the aeromonas sobria species complex.aeromonas sobria is a mesophilic motile aeromonad currently depicted as an opportunistic pathogen, despite increasing evidence of mutualistic interactions in salmonid fish. however, the determinants of its host-microbe associations, either mutualistic or pathogenic, remain less understood than for other aeromonad species. on one side, there is an over-representation of pathogenic interactions in the a. sobria literature, of which only three articles to date report mutualistic interactions; on th ...201729276504
involvement of the arg566 residue of aeromonas sobria serine protease in substrate specificity.aeromonas sobria serine protease (asp) is an extracellular serine protease secreted by the organism. here, we identified the amino acid residue of asp that contributes to substrate specificity by using both synthetic peptides and biological protein components. the results showed that the arginine residue at position 566 (arg-566) of asp, which is located in the extra occluding region of asp close to an entrance of the catalytic cavity, is involved in the substrate specificity. a substitutional p ...201729023605
a truncated sph12-38 with potent antimicrobial activity showing resistance against bacterial challenge in oryzias melastigma.antimicrobial peptides (amps) represent an efficient part of innate immunity and are found in a variety of life. among them histone 2a (h2a), as a promising class of amps, attracts great attention, but the in vivo mechanism of h2a derived amp is still less known. based on the acquisition of sphistin, a synthetic 38-amino acid h2a derived peptide from scylla paramamosain, as reported in our previous study, was truncated into three short fragments (sph12-38, sph20-38 and sph30-38) and further inve ...201728600196

aeromonas sobria serine protease (asp): a subtilisin family endopeptidase with multiple virulence activities.aeromonas sobria serine protease (asp) is secreted from aeromonas sobria, a pathogen causing gastroenteritis and sepsis. asp resembles saccharomyces cerevisiae kex2, a member of the subtilisin family, and preferentially cleaves peptide bonds at the c-terminal side of paired basic amino acid residues; also accepting unpaired arginine at the p1 site. unlike kex2, however, asp lacks an intramolecular chaperone n-terminal propeptide, instead utilizes the external chaperone orf2 for proper folding, t ...201728432839
