Summary

Affinities of the mutant cytidine deaminases for the transition-state analogue, 5-fluoropyrimidin-2-one ribonucleoside (3,4) hydrate, were found to decrease in rough proportion to kcat/Km over a range spanning several orders of magnitude, indicating the involvement of zinc coordination in the catalytic process rather than in substrate binding.
