[ jump to morphs ]

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

Structures
1DPE Conformation 2 [ PartsList ]
1DPP Conformation 1 [ PartsList ]

Description
An example of hinge motion between domains, the E. coli periplasmic dipeptide binding protein is larger than other periplasmic binding proteins, although similar in structure and motion. This protein has a phosphate-binding protein fold.
