Z-L-Lys-ONp hydrochloride has been used as a substrate for trypsin to monitor hydrolysis reaction using mass spectroscopy studies.
生化／生理作用
N-α-carbobenzoxy-L-lysine-p-nitrophenyl ester (Z-L-Lys-ONp) is a para-nitrophenol ester of N-CBZ-L-lysine. Z-L-Lys-ONp and other N-CBZ-amino acid p-nitrophenol esters are chromogenic substrates used for the differentiation and characterization of proteases and endopeptidases. It acts as a substrate for bromelain.

A new plant endopeptidase was obtained from unripe fruits of Bromelia balansae Mez (Bromeliaceae). Crude extracts were partially purified by ethanol fractionation. This preparation (redissolved ethanol precipitate, REP) showed maximum activity at pH 8.8-9.2, was very stable even at high

Mass spectrometry offers a potential means of measuring virtually all enzyme-catalyzed reactions by simultaneously measuring the concentrations of substrates, products, and intermediates where there are differences in mass between them. To perform these measurements the reaction mixture must be aged

Unripe fruit extracts of Bromelia balansae Mez (Bromeliaceae), whose principal endopeptidase is balansain I (isolated for anion exchange chromatography: pI = 5.45, molecular weight = 23192), exhibit a pH profile with a maximum activity around pH 9.0 and are inhibited

As part of a screening of latex endopeptidases from plants growing in Argentina, the presence of proteolytic activity in the latex of Funastrum clausum stems is reported. The proteases present in the crude extract showed the main characteristics of the

The kinetics of the trypsin-catalysed hydrolysis of the highly specific substrate N alpha-benzyloxycarbonyl-L-lysine p-nitrophenyl ester were studied under cryoenzymological conditions by 13C-n.m.r. spectroscopy at pH approx. 3.0. The kinetics of this reaction are shown to be in agreement with similar
