Synthesis and hydrolysis by arginyl-hydrolases of p-nitroanilide chromogenic substrates containing polyethylene glycol and D-gluconyl moieties.

Abstract

D-Gluconic acid and alpha-carboxymethyl-polyethylene-glycol-omega-methyl ether (PEG) (mol wt 550) were covalently bound at N alpha-amino group of H-Phe-Arg-pNa to study the effect on hydrolysis by arginyl-hydrolases of chromogenic substrates containing high hydrophilic and amphiphilic groups. For comparison, epsilon-aminocaproyl-, sarcosyl- and succinyl-Phe… (More)
