The β-galactosidase-catalysed hydrolyses of β-d-galactopyranosyl pyridinium salts. Rate-limiting generation of an enzyme-bound galactopyranosyl cation in a process dependent only on aglycone acidity
1. β-d-Galactopyranosyl pyridinium salts are well-behaved substrates for the β-galactosidase of Escherichia coli, catalysis occurring by the interaction of the salt itself with the normal active site of the protein. 2. logk(cat.) values for seven such salts show a linear relationship (correlation co...
