Abstract
As the result of [phage] P1-mediated cotransduction with serB from S. potsdam to the Escherichia coli/S. typhimurium hybrid 4617, 1 recombinant, L4004, was isolated which had a restriction-modification (R-M) system different from the SB and SP systems of its parents, and was designated SQ. The genes of SQ were allelic to those of the SB system of S. typhimurium and were shown by complementation in experiments to be functionally related to those of the K system of E. coli. Evidence that the SQ system in L4004 arose as the result of a recombination event within the hsdS genes of SB and SP is discussed.This publication has 1 reference indexed in Scilit:
