5-ALA is the precursor of all tetrapyrroles. 5-Aminolevulinate synthase (ALAS) catalyzes the production of 5-aminolevulinic acid (5-ALA) from glycine and succinyl-CoA. HemA from Rhodopseudomonas palustris (Rp-HemA) was reported to be a highly active ALAS. To understand the catalytic mechanism of Rp-HemA, the 2.05 A resolution crystal structure of Rp-HemA was solved. Open, half close and close conformations were observed in the substrate-free structures. Structure comparison and sequence alignment suggest the newly observed half close conformation may also be conserved in ALAS family. The pre-existed close and half close conformations in Rp-HemA may play a key role for its high activity. | |||
