Staphylococcal nuclease reviewed: a prototypic study in contemporary enzymology. IV. The nuclease as a model for protein folding.

Abstract

This is the last in a series of four articles in which the chemical, enzymological and crystallographic work on Ribonucleate (deoxyribonucleate)-3'-nucleotidohydrolase, EC 3.1.4.4 (staphylococcal nuclease, micrococcal nuclease) will be reviewed and correlated. This article discusses the use of the nuclease as a model system for the study of the mechanisms and energetics of the folding-unfolding reaction in proteins and for the study of the interrelationships between amino acid sequence and three-dimensional structure.
