Interaction of Escherichia coli dnaB and dnaC(D) gene products in vitro.

Abstract

Purified E. coli dnaB and dnaC(D) gene products interact physically and functionally in vitro. This interaction was demonstrated as follows: (a) A complex of dnaB and dnaC(D) gene products was isolated by gel filtration; ATP specifically was required for isolation of the complex. (b) The DNA-independent ribonucleoside triphosphatase activity associated with dnaB gene product was inhibited by dnaC(D) gene product. (c) The dnaC(D) gene product was protected from inactivation by N-ethyl-maleimide by the combination of dnaB gene product and ATP; this protection required ATP specifically.
