Polyphosphate kinase N-terminal domain superfamily (IPR036832)

Short name: PPK_N_dom_sf

Overlapping entries


Polyphosphate kinase (PPK) catalyses the formation of polyphosphate from ATP, with polyphosphate chain lengths of up to a thousand or more orthophosphate molecules.

The N-terminal domain of PPK consists of three alpha helices [PMID: 15947782] arranged in a close bundle fold with left-handed twist going up-and-down.
