1.14.14.33 physiological function EmoA is a reduced flavin mononucleotide-utilizing monooxygenase and EmoB is an NADH:flavin mononucleotide oxidoreductase. The two-enzyme system oxidizes EDTA to ethylenediaminediacetate (EDDA) and nitrilotriacetate (NTA) to iminodiacetate (IDA) with the production of glyoxylate -, 737490 1.14.14.33 physiological function enzyme catalyzes the first reaction of EDTA decomposition by cell extracts, an NADH-dependent process that is accompanied by O2 uptake -, 737483 1.14.14.33 physiological function enzyme catalyzes the first reaction of EDTA decomposition by cell extracts, an NADH2-dependent process that is accompanied by O2 uptake 737483 1.14.14.33 physiological function the first two steps of the catabolic pathway for EDTA consist of the sequential oxidative removal of two acetyl groups, resulting in the formation of glyoxylate. Ethylenediaminetriacetate (ED3A) is formed as an intermediate and N,N'-ethylenediaminediacetate is the end product. The enzyme complex consists of a monooxygenase, which catalyzes the cleavage of EDTA and ED3A while consuming oxygen and reduced flavin mononucleotide FMNH2, and an NADH2:FMN oxidoreductase that provides FMNH2 for the monooxygenase. The oxidoreductase can be replaced by other NADH2:FMN oxidoreductases -, 738508
