Journal ArticleDOI
Structure of the cro repressor from bacteriophage λ and its interaction with DNA
TL;DR: The three-dimensional structure of the 66-amino acid cro repressor protein of bacteriophage λ suggests how it binds to its operator DNA and suggests a pair of 2-fold-related α-helices of the represser seem to be a major determinant in recognition and binding.
Journal ArticleDOI
DNA-binding proteins
TL;DR: Structural and amino acid sequence comparisons suggest that this bihelical fold occurs in a number of proteins that regulate gene expression, and is an intrinsic part of the DNA-protein recognition event.
Journal ArticleDOI
Analysis of the sequence-specific interactions between Cro repressor and operator DNA by systematic base substitution experiments.
TL;DR: The binding affinities of purified Cro repressor to the chemically synthesized wild-type and mutant OR1 operators, consisting of all three possible base-pair substitutions and of thymine to uracil substitutions at each base- Pair position of the 17-base-pair operator sequence are measured.
Journal ArticleDOI
Lambda repressor recognizes the approximately 2-fold symmetric half-operator sequences asymmetrically.
Akinori Sarai,Yoshinori Takeda +1 more
TL;DR: The observed asymmetric recognition of the lambda repressor dimer suggests that no recognition code governs amino acids and DNA bases in protein-DNA interactions.
Journal ArticleDOI
Protein-DNA conformational changes in the crystal structure of a lambda Cro-operator complex
TL;DR: The structure of a complex of bacteriophage lambda Cro protein with a 17-base-pair operator with 3.9-A resolution confirms the general features of the model previously proposed for the interaction of Cro with DNA.
