Function
Involved in the biodegradation of xenobiotic compounds, such as nitrobenzene and 4-chloronitrobenzene (4-CNB) (PubMed:16517619). CnbZ preferentially catalyzes the deamination of 2-amino-5-chloromuconate (2A5CM) to yield 2-hydroxy-5-chloromuconate (2H5CM). Also able to catalyze the deamination of 2-aminomuconate to yield 2-hydroxymuconate, which spontaneously converts into its keto form, 2-oxalocrotonate.
