The operator-binding domain of lambda repressor: structure and DNA recognition.

Abstract

The structure of the operator-binding domain of the lambda repressor has been determined at 3.2 A resolution. This domain contains an extended N-terminal arm and five alpha-helices. Model-building studies of the repressor-operator complex suggest that alpha-helices, especially the N-terminal parts of these helices, may provide a useful surface for protein-DNA interactions.
