THE HYDROLYSIS OF p-NITROPHENYL ESTERS OF α-AMINO ACIDS BY N-LAUROYL l OR d -HISTIDINE IN CATIONIC MICELLES

In order to investigate the enantioselectivity of enzyme-catalyzed reactions the hydrolysis of l and d-SEP were carried out using optically active catalyst, l and d-LauHis, in the presence of the mixed micelles with an optically active surfactant, l-TALAI, or inactive surfactant, CTABr. The enantiometric rate ratios of 1.5–1.6 were obtained in these systems with both surfactants.
