WebApr 24, 1998 · The nature of the rate-limiting step catalyzed by PTPs and DSPs is not entirely resolved. There are kinetic data to suggest that the rate-limiting step of PTP catalysis is the rate of phosphoryl-enzyme formation (25). This would imply that the cysteinyl-phosphate intermediate would not accumulate appreciably within the wild-type enzyme. WebNov 1, 2015 · Later, the unique level of detail KIEs provided led to deeper questions about the potential role of protein motions in PTP catalysis. The recent discovery that such motions are responsible for different catalytic rates between PTPs arose from questions originating from KIE data showing that the transition states and chemical mechanisms …
