We provide here the first direct evidence that D-aspartyl residues in peptides are substrates for the L-isoaspartyl/D-aspartyl protein carboxyl methyltransferase (EC 2.1.1.77). We do this by showing that D-aspartic acid beta-methyl ester can be isolated from carboxypeptidase Y digests of enzymatically methylated D-aspartyl-containing synthetic peptides. The specificity of this reaction is suppo...
The aim of this study was to investigate the interaction of Candida tropicalis with three different human cell lines: TCC-SUP (epithelial cells from urinary bladder), HeLa (epithelial cells from cervical carcinoma) and Caco-2 (epithelial cells from colorectal adenocarcinoma). In particular we sought to assess the degree of cell damage and activity reduction induced by C. tropicalis adhesion and...
Aminopeptidase A (aspartate aminopeptidase, EC 3.4.11.7) was purified 2000-fold from pig kidney cortex. The essential step in the purification was chromatography on an immunoadsorbent column prepared from a rabbit antiserum raised against pig intestinal aminopeptidase A. Glutamyl and aspartyl substrate were attacked most rapidly and their hydrolyses were stimulated by Ca2+. The 2-naphthylamide ...
Secretion of proteolytic and chitinolytic enzymes is a hallmark of infection processes of Metralhizium anisopliae in response to host (insect) cuticular signals. The regulation of these enzymes (subtilisin-like proteases [Pr1a and Pr1b], trypsin-like proteases [Pr2], metalloproteases, aspartyl proteases, aminopeptidase, and chitinases) and a hydrophobin was investigated by Northern analysis and...
Cultured bovine capillary endothelial (BCE) cells were found to synthesize and secrete high molecular mass heparan sulfate proteoglycans and glycosaminoglycans, which bound basic fibroblast growth factor (bFGF). The secreted heparan sulfate molecules were purified by DEAE cellulose chromatography, followed by Sepharose 4B chromatography and affinity chromatography on immobilized bFGF. Most of t...
Background: The Candida albicans is one of the most important global opportunistic pathogens, and the incidence of candidiasis has increased over the past few decades. Despite the established role of skin in defense against fungal invasion, little has been documented about the pathogenesis of Candida species when changing from normal flora to pathogens of vaginal and gastrointestinal epithelia....
