Consequently, substitution of Val371 to isoleucine might prevent the full development of the active conformation. This hypothesis is further con- firmed by the results of FIX proteolytic...

In the absence of CIII, CII is rapidly degraded by the ATP- dependent ... However, this proteolysis is much slower in vitro, because of a lack of chaperone machin- ery. The in vitro proteolysis requires ATP [14]. We examined the proteolysis of purified r 32 -C-his (1.2 ... CIII- mediated inhibition of proteolysis of r 32 by HflB is unknown. We tried to address this issue by studying the effects of CIII and CIIIC on the proteolysis of Keywords antiproteolytic activity;...
