Staphylococcal nuclease reviewed: A prototypic study in contemporary enzymology. I isolation; physical and enzymatic properties

Abstract

This is the first of a series of four articles in which the chemical, enzymological, and crystallographic work on Ribonucleate (deoxyribonucleate)-3′-nucleotidohydrolase, EC 3.1.4.7, (Staphylococcal nuclease, Micrococcal nuclease) will be reviewed and correlated. This article discusses the purification of the enzyme and its general physical and enzymological properties. Subsequent articles will deal with specific studies of the nucleotide binding site, crystallographic studies of a nuclease-inhibitor complex, use of the nuclease as a model for protein folding and possible mechanisms for the action of the enzyme.
