Motion in Catabolite Gene Activator Protein (CAP) [cap]

[ jump to morphs ]

Classification Known Domain Motion, Hinge Mechanism [D-h-2]

Structures 1G6N Both forms 1GAP obsolete 3GAP obsolete [ PartsList ]

Description 1 interdomain linkage and 1 hinge. Comparison of subunits in the dimer reveals that the small domain has rotated ~30 degree closer to the large domain in one subunit. Motion is evident in comparing different subunits in the asymmetric unit. Single data bank identifier applies for both forms.
