Like ... compared with 40% for the control (r 32 alone, Fig. 2C). The inhibitory action of CIIIC on the proteolysis of r 32 by HflB was also assayed in the presence of CIIIC (60 lm) instead of CIII (Fig. 2B). ... mode of action for kCIII would be independent of the HflB substrate. In this study, we tested the ability of CIII to protect r 32 from HflB digestion. The inhibition of HflB-mediated proteolysis of...
