Chains	Enzyme Name	Description	Catalytic Residues
A	pyruvate, phosphate dikinase M-CSA #207	Pyruvate phosphate dikinase (PPDK) catalyses the interconversion of ATP, Pi , and pyruvate with AMP, PPi , and PEP. The enzyme has a three-domain structure consisting of consecutive N-terminal, central His455, and C-terminal domains. The nucleotide binding site is located within the N-terminal part of the polypeptide chain, whereas the pyruvate/PEP binding site is located within the C-terminal part of the chain. The first and second partial reactions take place in the active site formed at the interface of the N-terminal domain (which binds Mg(II), ATP, and Ppi) and the central domain (which contributes the catalytic His455) in PPDK conformer 1. The third partial reaction takes place in the active site formed at the interface of the C-terminal domain (which binds Mg(II) and pyruvate) and the central domain (which contributes the phosphorylated His455) in PPDK conformer 2.
