A mutation defining ultrainduction of the Escherichia coli gal operon.

A Golding¹, M J Weickert, J P Tokeson, S Garges, S Adhya.

Abstract

Tn10 insertion in the galS (ultrainduction factor) gene of Escherichia coli allows the gal operon to be constitutively expressed at a very high level, equal to that seen in a delta galR strain in the presence of an inducer. The insertion has been mapped by criss-cross Hfr matings and by marker rescue into Kohara phages at 46 min on the E. coli chromosome.
