Differential recognition of OR1 and OR3 by bacteriophage 434 repressor and Cro.

The Journal of biological chemistry - 15 Nov 1993

Koudelka G B, Lam C Y

Abstract excerpt

The developmental decisions of bacteriophage 434 depend on the ability of 434 repressor and Cro to bind OR1 and OR3 with different relative affinities; repressor binds OR1 tighter than OR3, whereas Cro slightly prefers OR3 over OR1. Studies with operator mutants show that repressor's lower relative affinity for OR3 results from a deviation in the sequence of OR3 from consensus; an A-->G change at position 4 in...
