SECRETED ASPARTIC PROTEINASE (SAP2) FROM CANDIDA ALBICANS COMPLEXED WITH A70450
OverviewOverview
BACKGROUND: Infections caused by Candida albicans, a common fungal, pathogen of humans, are increasing in incidence, necessitating development, of new therapeutic drugs. Secreted aspartic proteinase (SAP) activity is, considered an important virulence factor in these infections and might, offer a suitable target for drug design. Amongst the various SAP isozymes, the SAP2 gene product is the major form expressed in a number of C., albicans strains. RESULTS: The three-dimensional structures of SAP2, complexed with the tight-binding inhibitor A70450 (a synthetic hexapeptide, analogue) and with the general aspartic proteinase inhibitor pepstatin A, (a microbial natural product) have been determined to 2.1 A and 3.0 A, resolution, respectively. Although the protein structure retains the main, ... [(full description)]
