Crystal Structure of E.coli MenH
Function
[MENH_ECOLI] Catalyzes a proton abstraction reaction that results in 2,5-elimination of pyruvate from 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate (SEPHCHC) and the formation of 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC). Is also able to catalyze the hydrolysis of the thioester bond in palmitoyl-CoA in vitro.[1] [2]
About this Structure
4gdm is a 3 chain structure with sequence from Escherichia coli k-12. Full crystallographic information is available from OCA.
