A, B	PF00391	PEP-utilising enzyme, mobile domain (PEP-utilizers)	PEP-utilising enzyme, mobile domain	This domain is a "swivelling" beta/beta/alpha domain which is thought to be mobile in all proteins known to contain it.	Domain
A, B	PF02896	PEP-utilising enzyme, PEP-binding domain (PEP-utilizers_C)	PEP-utilising enzyme, PEP-binding domain	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].	Domain
