L 2 amino 4 chloropent 4 enoate dehydrochlorinase

In enzymology, a L-2-amino-4-chloropent-4-enoate dehydrochlorinase (EC 4.5.1.4), an enzyme, catalyzes the chemical reaction.

L-2-amino-4-chloropent-4-enoate + H₂O ⇌ 2-oxopent-4-enoate + chloride + NH₃

Thus, the two substrates of this enzyme are L-2-amino-4-chloropent-4-enoate and H₂O, whereas its 3 products are 2-oxopent-4-enoate, chloride, and NH₃.

This enzyme belongs to the family of lyases, specifically the class of carbon-halide lyases. The systematic name of this enzyme class is L-2-amino-4-chloropent-4-enoate chloride-lyase (adding H₂O deaminating; 2-oxopent-4-enoate-forming). Other names in common use include L-2-amino-4-chloro-4-pentenoate dehalogenase, and L-2-amino-4-chloropent-4-enoate chloride-lyase (deaminating).
