Aminolevulinic acid synthase (ALAS) is the initial enzyme of heme biosynthesis in humans, animals and some bacteria. It catalyzes the condensation of succinyl-CoA and glycine to yield aminolevulinic acid (ALA), Coenzyme A and CO2. To clarify details of its catalytic mechanism thirteen Rhodobacter capsulatus ALAS (ALASRc) variants were generated, purified and kinetically characterized. Variants of ALASRc for trapping the second intermediate in the ALAS reaction mechanism, 2-amino-3-ketoadipate, in cysteine-free ALAS background were generated. By performing single turnover experiments we were able to detect the second quinonoid. With the reaction with O-methylglycine we verified the occurrence of the first quinonoid as a clear indication for...
