'''''The movie''' depicts the catalytic reaction involving three in-line phosphotransfers and the accompanied protein conformational transitions. This is a model based on crystal structures of PPDK from '''Clostridium symbiosum''' in the two extreme conformational states shown to the left and of complexes bound to substrate analogs, phosphonopyruvate and 5'-adenylyl-β,γ-imidodiphosphate (AMPPNP). The nucleotide binding subdomains are colored green and blue. The PEP binding domain is colored cyan. The His-domain is colored yellow, and the linker segments that connect the His-domain to the partner domains are colored red. Ligands and the catalytic histidine are depicted in stick models with the atomic color scheme: Carbon – gray, Nitrogen – blue, Oxygen – red, Phosphorous – green, Magnesium – magenta. Note that the reaction pregresses in the movie in the reverse direction; steps 3 and 2 occur first followed by step 1. The movie was created by Kap Lim and osnat Herzberg''<br> | '''''The movie''' depicts the catalytic reaction involving three in-line phosphotransfers and the accompanied protein conformational transitions.
