title: Depression of prolylendopeptidase activity in the delayed hypersensitive guinea pig skin lesion induced by bovine gamma-globulin.
abstract: Prolylendopeptidase activity was increasingly depressed with time from 6 to 24 hr after the start of sensitization in the delayed hypersensitive guinea pig skin lesion induced by bovine gamma-globulin as an antigen. The remarkably depressed activity of the enzyme in the violently inflamed skin began to be restored slowly 48 hr after sensitization, and its activity was ultimately recovered to the original level by 504 hr after a single sensitization in vivo. Depression of the enzymatic activity is caused by a novel prolyendopeptidase inhibitor, whose amino acid composition is 7 Glu, 1 Ser, 2 Gly, 1 Ala, 2 Pro, and 1 Val, generated by inflammation.
