This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is L-cysteine-S-conjugate thiol-lyase (deaminating; pyruvate-forming). Other names in common use include cysteine conjugate β-lyase, glutamine transaminase K/cysteine conjugate β-lyase, and L-cysteine-S-conjugate thiol-lyase (deaminating). It employs one cofactor, pyridoxal phosphate.
Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1W7L, 1W7M, and 1W7N.
