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.
