We studied these enzymes in a number of mutants deficient in recombination or repair functions(rec, uvr)and in competent cells. The recA mutant studied had lower ATPase II activity, while competent cells had higher ATPase I activity, in comparison with the parental strain not brought to competence. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-130-1-113
