Degradation of side-chains of N-(2-hydroxypropyl)methacrylamide copolymers by lysosomal thiol-proteinases.

Abstract:

:N-(2-Hydroxypropyl)methacrylamide copolymers bearing oligopeptide side-chains terminating in p-nitroaniline (NAp) were incubated with rat liver lysosomal enzymes in the presence of the thiol glutathione, and the rate of p-nitroaniline release was measured. Twelve of the 16 side-chains investigated were hydrolysed to release p-nitroaniline and in all but one case degradation was partially or totally inhibited by leupeptin. The effect of substrate concentration on the degradation of the most readily cleaved side-chain, -Ala-Gly-Val-Phe-NAp, was measured.
