چکیده

Background: IseA from Bacillus subtilis is an inhibitor protein against DL-endopeptidases including synthetic lethal autolysins. Results: We solved the solution structure of IseA using NMR. Titration with LytF DL-endopeptidase indicated interaction sites around the loop region. Conclusion: The IseA structure revealed a novel “hacksaw”-like fold with a characteristic inhibitory loop. Significance: The results suggest a new inhibition mechanism of IseA with a unique loop.

Cloning of Minor Autolysin of Streptococcus Pneumoniae

Abstract Background and Objective: Increased antibiotic resistant strains and inadequacy of current vaccines against pneumococcal infections necessitate the study of novel protein antigens. It seems that minor autolysin of Streptococcus pneumoniae may have antigenicity. Thus, we aimed at cloning its gene for the first time. Material and Methods: After DNA extraction of Streptococcus pneumoniae ...

Design, Synthesis and Biological Evaluation of Novel Peptide-Like Analogues as Selective COX-2 Inhibitors

A new series of peptide-like derivatives containing different aromatic amino acids andpossessing pharmacophores of COX-2 inhibitors as SO2Me or N3 attached to the para positionof an end phenyl ring was synthesized for evaluation as selective cyclooxygenase-2 (COX-2)inhibitors. The synthetic reactions were based on the solid phase peptide synthesis methodusing Wang resin. One of the analogues, i...

P82: Anxiolytics Effect of α-Galycoceramide: As Novel Inhibitor of Glucocorticoid in Social Isolated Rats

α-Galycoceramide (α-Galcer) or the common name of krn7000 is an α-gelasphin derivative. The α-Galcer structure consists of a galactose combined with a ceramide in an α-configuration. Social isolation (SI) has been linked with enhanced inflammation, through modifications in transcriptional pathways linked with glucocorticoid, to stress. Our hypothesis is to investigate mediatory role of glucocor...

C-Terminal Propeptide of BKA has a Protease Sensitive Structure Without any Inhibitory Effect on BKA

In our previous study, we compared the two α-amylase enzymes from Bacillus sp.KR8104, BKA∆(N44) and BKA∆(N44C193) which is the secreted form of it. The results indicated that the presence of 193 amino acids propeptide in the C-terminal of BKA∆(N44) changed its enzymatic parameters like an uncompetitive inhibitor in comparison to BKA∆(N44C193). In the present study, we cloned the DNA sequence of...
