EDTA and nitrilotriacetate (a structural homolog of EDTA) degradation
pathway. The enzymes are EDTA monooxygenase (encoded by emoA),
NADH:FMN oxidoreductase (emoB), and
ethylenediaminediacetate/iminodiacetate oxygenase (idaA). Each
enzymatic step removes an acetate group as a glyoxylate. ED3A,
ethylenediaminetriacetate; EDDA, ethylenediaminediacetate;
EDMA, ethylenediaminemonoacetate; ED, ethylenediamine;
NTA, nitrilotriacetate; IDA, iminodiacetate; Gly,
glycine.
