Amplification of the ArgF region in strain HfrP4X of E. coli K-12.

Abstract

In E. coli K-12 the argF gene is flanked by ISI sequences in direct repeat. Mutants that overproduce the argF-coded enzyme ornithine transcarbamylase can be selected; we have shown that in one class of these mutants there is an approximately forty five-fold amplification of the region bounded by the ISI repeats. This class of mutants has been detected only in strains in which the F-factor is integrated in cis to the region.
