3.5.99.10 2-iminobutanoate/2-iminopropanoate deaminaseIUBMB Comments
This enzyme, which has been found in all species and tissues examined, catalyses the hydrolytic deamination of imine intermediates formed by several types of pyridoxal-5'-phosphate-dependent dehydratases, such as EC 4.3.1.19, threonine ammonia-lyase and EC 4.3.1.17, L-serine ammonia-lyase. The reactions, which can occur spontaneously, are accelerated to minimize the cellular damage that could be caused by these reactive intermediates.

proposed mechanism of RidA-dependent enamine and imine catalysis, overview. Consistent with RidA enzymes acting on iminium ion substrates, when iminium ions are generated directly via FAD-dependent oxidases, inclusion of RidA increases the rate of hydrolysis in vitro. But it remains unclear whether RidA decreases enamine accumulation by binding the enamine and facilitating both iminium ion formation and subsequent hydrolysis or whether RidA decreases enamine levels simply through increased consumption of its iminium ion tautomer

enzyme assay is coupled using Crotalus adamanteus L-amino acid oxidase, bovine liver catalase, and the Rid enzyme. When arginine is used as a LOX substrate, representatives from the Rid1, Rid2 and Rid3 subfamilies appear to have more deaminase activity than RidA

addition of purified RidA to the Salmonella enterica IlvA reactions increases the rate of ketoacid formation, showing that RidA catalyzes the hydrolysis of enamines derived from threonine (2-aminocrotonate, 2AC) and serine (2-aminoacrylate, 2AA)
