FIGURE 1. Degradation Pathway for EDTA and NTA.

FIGURE 1

(A) EDTA: EmoA and EmoB together remove acetate group as glyoxylate from EDTA and ethylenediaminetriacetate (ED3A). IdaA further removes acetate group from ethylenediaminediacetate (EDDA) and ethylenediaminemonoacetate (EDMA) producing ethylenediamine (ED). (B) NTA: EmoA and EmoB can also deacetylate NTA to produce iminodiacetate (IDA), which is further deacetylated by IdaA to glycine.
