the role of CSE in this reaction pathway is to convert l-cystathionine into l-cysteine whilst generating α-ketobutyrate and ammonia (Fig. 1). The reaction proceeds via an α,γ-elimination mechanism where the C–γ–S bond of l-cystathionine is specifically cleaved to yield l-cysteine.12 Defects in this metabolic pathway are associated with cystathioninuria, l-cysteine deficiency and subsequent impairment of glutathione metabolism, as well as higher plasma homocysteine concentrations.13, 14, 15, 16, 17 Besides its role in the conversion of l-cystathionine into l-cysteine, studies have also shown that CSE can utilize l-cysteine as a substrate for producing H2S via an α,β-elimination reaction (Fig. 1).18, 19, 20 However, to date, no reports have clearly demonstrated the residues that affect CSE-mediated H2S production. |

Cystathionine β-synthase (CBS) is a pyridoxal 5'-phosphate (PLP)-dependent enzyme that catalyzes the condensation of homocysteine with serine to generate cystathionine. |
