[Effect of histidine analogs and histidyl-containing dipeptides on the decarboxylase activity of Micrococcus sp. n. histidine decarboxylase].
L-Histidinol and L-histidine hydroxamate were shown to inhibit competitively histidine decarboxylase from Micrococcus sp. n responsible for histamine biosynthesis. Constants of their inhibitory effect were found. Histidyl-containing dipeptides did not exhibit the pronounced inhibitory effect. The rate of inhibition was increased after esterification of histidyl dipeptide. Kinetics of the histidine decarboxylase inhibition by L-histidyl-L-leucine methyl ester was studied.
