The stereochemical course of the phospho group transfer catalyzed by mutant (S102C) alkaline phosphatase from Escherichia coli was investigated by using /sup 31/P nuclear magnetic resonance spectroscopy. Transphosphorylation from 4-nitrophenyl (R/sub P/)-/sup 17/O, /sup 16/O, /sup 18/O)phosphate to (S)-propane-1,2-diol occurs with overall retention of configuration at phosphorus. This result is consistent with the view that the hydrolysis of substrates by this mutant enzyme proceeds by way of a covalent phosphoenzyme intermediate in the same manner as the wild-type alkaline phosphatase.
