  •   Molecular Description Hide
    Classification: Gene Regulation/dna
    Structure Weight: 12093.58
    Molecule: DNA (5'-D(*TP*AP*TP*CP*GP*AP*TP*A)-3')
    Polymer: 1 Type: dna Length: 8
    Chains: R, S
    Details: 50% OCCUPANCY IN THE OUTERMOST POSITIONS
    Molecule: PROTEIN (CRO REPRESSOR)
    Polymer: 2 Type: protein Length: 65
    Chains: A
    Mutation: INSERTION (K56-DGEVK)
    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.
    Organism: Enterobacteria phage lambda
