PROTEIN (CRO REPRESSOR) A 65 Enterobacteria phage lambda Mutation: D57D, G58G, E59E, V60V, K61K, P62P, F63F, P64P, S65S, N66N
Details: WILDTYPE CRO DOES NOT FORM STABLE MONOMERS. THE ENGINEERED-MONOMER PRESENTED HERE CONTAINS A 5-RESIDUE INSERTION [DGEVK] FOLLOWING K 56. THE FIRST 2 RESIDUES OF THIS INSERTION ALLOW THE FORMATION OF A BETA-TURN. THE REMAINING 3 RESIDUES MIMIC RESIDUES OF THE WILDTYPE DIMER INTERFACE, ALLOWING STABILIZING INTERACTIONS TO BE MAINTAINED. THE OVERALL STRUCTURE OF THIS MONOMER IS QUITE SIMILAR TO A SUBUNIT OF THE WILDTYPE DIMER.
