Ectoine synthase

The enzyme ectoine synthase catalyzes the chemical reaction


 * (2S)-4-acetamido-2-aminobutanoate $$\rightleftharpoons$$ L -ectoine + H2O

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.
