Abstract
Glycylproline p-nitroanilide is hydrolysed in lymphocytes from human blood exclusively by dipeptidyl peptidase IV. This was demonstrated by specific inhibition with N-alanylprolyl-O-(4-nitrobenzoyl)hydroxylamine and di-isopropyl phosphorofluoridate and by studying the membrane localization of dipeptidyl peptidase IV and determining specific dipeptidyl peptidase II activity. Additional evidence that dipeptidyl peptidase IV is a marker for T-lymphocytes, obtained from determinations of biochemical activity on intact lymphocyte preparations and correlation studies with other T-cell markers, is also presented.
