This entry represents a TIM barrel domain found at the C terminus of a number of PEP (phosphoenolpyruvate)-utilising proteins. In PPDK (Pyruvate phosphate dikinase) this C-terminal domain has been shown to be a PEP-binding domain [1]. [1]. 18052212. Swiveling domain mechanism in pyruvate phosphate dikinase..

This domain is a "swivelling" beta/beta/alpha domain which is thought to be mobile in all proteins known to contain it. [1]. 8610096.

This HMM recognizes a distinct clade of phophoenolpyruvate (PEP)-dependent enzymes. Most members are known or deduced to function as the phosphoenolpyruvate-protein phosphotransferase (or enzyme I) of PTS sugar transport systems. However, some species with both a member of this family and a homolog of the phosphocarrier protein HPr lack a IIC component able to serve as a permease. An HPr homolog designated NPr has been implicated in the regulation of nitrogen assimilation, which demonstrates that not all phosphotransferase system components are associated directly with PTS transport.
