Abstract

A series of substituted glycogen esters have been evaluated as substrates for [alpha]-chymotrypsin. The second order base-catalyzed hydrolysis constants for these compounds have also been determined.

Four substrates for [alpha]-chymotrypsin have been found to exhibit unusual kinetic behavior at very high concentrations in the presence of [alpha]-chymotrypsin. It has been shown that these data can be the result of two molecules of substrate combining with each enzyme active site.

A hypothesis concerning the enzyme-substrate complex is offered which helps to correlate the data given in this work.
