cystathionine gamma lyase

General Information (Source: NCBI Gene,UniProt)

Text mining Term	cystathionine gamma lyase
UniProt ID	CGL_RAT
Name	PRB-RA Gamma-cystathionase Cystathionine gamma-lyase Probasin-related antigen
Gene Names	Cth
Taxonomy	Rattus norvegicus

General annotation

Function	Catalyzes the last step in the transsulfuration pathway from methionine to cysteine. Has broad substrate specificity. Converts cystathionine to cysteine, ammonia and 2-oxobutanoate. Converts two cysteine molecules to lanthionine and hydrogen sulfide. Can also accept homocysteine as substrate. Specificity depends on the levels of the endogenous substrates. Generates the endogenous signaling molecule hydrogen sulfide (H2S), and so contributes to the regulation of blood pressure (By similarity).
Subcellular location	Cytoplasm.
