This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is (2S)-4-acetamido-2-aminobutanoate (L-ectoine-forming). Other names in common use include N-acetyldiaminobutyrate dehydratase, N-acetyldiaminobutanoate dehydratase, L-ectoine synthase, EctC, and 4-N-acetyl-L-2,4-diaminobutanoate hydro-lyase (L-ectoine-forming). This enzyme participates in glycine, serine and threonine metabolism.
