Z-Lys-ONp HCl

White to off-white powder

Z-L-Lys-ONp hydrochloride has been used as a substrate for trypsin to monitor hydrolysis reaction using mass spectroscopy studies.

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.
