General annotation (Comments)

Function

Catalyzes the alpha,beta-elimination reaction of D-cysteine and of several D-cysteine derivatives. It could be a defense mechanism against D-cysteine By similarity. HAMAP-Rule MF_01045

Catalytic activity

D-cysteine + H2O = H2S + NH3 + pyruvate. HAMAP-Rule MF_01045

Cofactor

Pyridoxal phosphate By similarity.

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the ACC deaminase/D-cysteine desulfhydrase family.
