CRYSTAL STRUCTURE OF SUBTILISIN-PROPEPTIDE COMPLEX
Overview
We report here the crystallographic structure determination of an, autoprocessed (Ser221Cys)-subtilisin E-propeptide complex at 2.0 A, resolution. The subtilisin domain sequence has a single substitution, (Ser221Cys) which has been shown to block the maturation process prior to, degradation of the propeptide domain (77 residues) that acts as an, intramolecular chaperon. This mutation, however, did not prevent the, enzyme from cleaving its propeptide domain with a 60-80% efficiency. The, current determination is the first example of a subtilisin E-propeptide, complex which has been autoprocessed. A previous structure determination, of a BPN'-prosegment complex has been reported in which the subtilisin, domain was extensively mutated and a calcium binding loop was deleted., Further, in this ...
