Three B. subtilis dna gene mutations, dnaC30 and ts56 causing defects in elongation and ts199 causing a defect in the initiation of replication, were mapped in the gene by transformation and DNA sequencing. Both dnaC30 and ts56 have been located near the amino-termina-l end of the B. subtilis DnaC protein. In contrast, ts199 has been located near the carboxy-terminal of the protein. Our results indicate that the B. subtilis dnaC gene encodes a counterpart of the E. coli dnaB helicase., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/13500872-141-3-641
