Protein attributes

Sequence length	1278 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Mediates the incorporation of phosphate into alpha-glucan, mostly at the C-6 position of glucose units By similarity.
Catalytic activity	ATP + alpha-glucan + H2O = AMP + phospho-alpha-glucan + phosphate.
Cofactor	Magnesium By similarity.
Subunit structure	Homodimer By similarity.
Domain	The N-terminal domain contains the alpha-glucan binding site, the central domain the pyrophosphate/phosphate carrier histidine, and the C-terminal domain the ATP binding site By similarity.
Miscellaneous	The reaction takes place in three steps, mediated by a phosphocarrier histidine residue located on the surface of the central domain. The two first partial reactions are catalyzed at an active site located on the C-terminal domain, and the third partial reaction is catalyzed at an active site located on the N-terminal domain. For catalytic turnover, the central domain swivels from the concave surface of the C-terminal domain to that of the B-terminal domain By similarity.
Sequence similarities	Belongs to the PEP-utilizing enzyme family.
Sequence caution	The sequence CAB45080.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAB79355.1 differs from that shown. Reason: Erroneous gene model prediction.
