Protein
Phosphoenolpyruvate-protein phosphotransferase
Gene
ptsI, MPN_627, MP215
Organism
Mycoplasma pneumoniae (strain ATCC 29342 / M129)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr) By similarity.

Catalytic activityi

Phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)-phospho-L-histidine.

Cofactori

Magnesium By similarity.

Miscellaneousi

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 N-terminal domain, and the third partial reaction is catalyzed at an active site located on the C-terminal domain. For catalytic turnover, the central domain swivels from the concave surface of the N-terminal domain to that of the C-terminal domain By similarity.
