Abstract
An hypothesis for the active site and mechanism of action of ribonuclease is presented. In the hydrolysis of cytidine 2[image],3[image]-phosphate a histidine in the acid form transfers a proton to the 2[image]-oxygen atom of the nucleotide and a proton from water (or an alcohol) is transferred to another histidine. In the cyclization of an ester of cytidine 3[image]-phosphate, such as ribo-nucleic acid, the function of these two histidines is reversed.This publication has 6 references indexed in Scilit:
