Disruption of an ATP-dependent isomerization of the recA protein by mutation of histidine 163.

The Journal of biological chemistry - 15 Jan 1991

Muench K A, Bryant F R

Abstract excerpt

We have used site-directed mutagenesis to replace histidine 163 of the recA polypeptide with an alanine residue. The new [Ala-163]recA protein catalyzes single-stranded (ss) DNA-dependent ATP hydrolysis with a turnover number that is similar to that of the wild-type recA protein. Despite being proficient in ssDNA-dependent ATP hydrolysis, the [Ala-163]recA protein is unable to promote the ATP-dependent...
