UniprotKB/SwissProt ID: Q9VRD9 (Q9VRD9)
Gene Name:
Cbs
Organism: Drosophila melanogaster (Fruit fly)
Function: Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L-homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine. Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons
