What it does, reaction by reaction

1 reactions

Methionine Cycle / Transmethylation (SAM Cycle, homocysteine) Amino Acid & Nitrogen Metabolism · Cytosol

step 7 Irreversible/directional

Cystathionine + H₂O → L-cysteine + α-ketobutyrate + NH₄⁺

Converts Cystathionine H2O into Cysteine Alpha-ketobutyrate NH4+

Notes

Cystathionine γ-lyase (CGL/CSE) is PLP-dependent and completes transsulfuration. α-Ketobutyrate is oxidatively decarboxylated to propionyl-CoA and can yield succinyl-CoA through the biotin- and cobalamin-dependent propionate pathway.
