DNA repair in competent cells of Bacillus subtilis
Abstract
A series of isogenic transformable strains of Bacillus subtilis carrying the uvr-19 or rec-43 mutation or both were constructed. Both mutations made competent cells defective in repairing UV-irradiated cellular or transforming DNA, and their effects were additive in a doubly deficient strain, suggesting that two repair processes, requiring uvr-19+ and rec-43+ gene products, are independently functional in competent cells of B. subtilis.
