Hydrolysis catalyzed with a resin containing histidine groups

Abstract: A histidine-containing polymer was synthesized in which the amino group of the histidine was attached chemically via an azide coupling method to the carboxylic acid of Amberlite IRC-50. The resultant polymer was applied as a catalyst for hydrolysis of p-nitrophenyl acetate (PNPA). PNPA in aqueous solution was hydrolyzed at 25°C with a phosphate buffer (pH 7.8). The observed kinetics obeyed Michaelis-Menten kinetics. The reaction rates at various temperature were measured. The activation parameters, preexponent… Show more

“…35 Therefore we have considered histidine-based lipopeptides as potential self-assembled organocatalysts for hydrolysis reactions in water. Indeed hydrolysis catalyzed by histidine-related compounds is widely documented in the case of simple esters, [36][37][38][39][40][41][42] phosphoesters, [43][44][45][46][47][48][49][50][51][52] or even DNA. 53,54 As a rst step we initiated this study considering the widely used ester (p-nitrophenyl acetate) as model substrate.…”
