The structure of succinyl-CoA synthetase bound to the succinyl-phosphate intermediate clarifies the catalytic mechanism of ATP-citrate lyase. C atoms are yellow and purple for the succinyl-phosphate complex, green for the wild type with succinate and phosphate, and cyan for the mutant with succinate and phosphate. Water molecules are red for the succinyl-phosphate complex, pink for the wild type and grey for the mutant with succinate and phosphate. Other atoms are coloured according to type. Distances from the side-chain carbonyl O atom of Gln105α to the magnesium ion and from the carboxylate O atom of Glu105α to the water molecules are shown in Å. |
