Three dominant proteins (41, 48, and 49 kDa) were detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) in purified preparations of the extracellular aspartyl proteinase (AP) of Candida albicans. All three proteins bound to the specific carboxyl proteinase ligand, pepstatin A, and were associated with maximum AP activity. The N-terminal amino acid sequence for the 48-...
It was recently proposed that Candida parapsilosis represents a complex composed of three closely related species, i.e., C. parapsilosis sensu stricto, C. orthopsilosis, and C. metapsilosis. The aim of this study was to describe the distribution of C. parapsilosis complex isolates among clinical samples. We also evaluated antifungal susceptibility profiles, in vitro presence of lipase and secre...
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...
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 ...
