Motion in E. coli. Periplasmic Dipeptide Binding Protein [ecpdpbp]

[ jump to morphs ]

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

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

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.
