SOLUTION STRUCTURE OF STAPHOSTATIN A FORM STAPHYLOCOCCUS AUREUS CONFIRMS THE DISCOVERY OF A NOVEL CLASS OF CYSTEINE PROTEINASE INHIBITORS.
Overview
A series of secreted proteases are included among the virulence factors, documented for Staphylococcus aureus. In light of increasing antibiotic, resistance of this dangerous human pathogen, these proteases are, considered as suitable targets for the development of novel therapeutic, strategies. The recent discovery of staphostatins, endogenous, highly, specific, staphylococcal cysteine protease inhibitors, opened a, possibility for structure-based design of low molecular weight analogues., Moreover, the crystal structure of staphostatin B revealed a distinct, folding pattern and an unexpected, substrate-like binding mode. The, solution structure of staphostatin A reported here confirms that, staphostatins constitute a novel, distinct class of cysteine protease, inhibitors. In addition, the structure knowledge-based mutagenesis studies, shed light on individual structural features of staphostatin A, the, inhibition mechanism, and the determinants of distinct specificity of, staphostatins toward their target proteases.
