BACKGROUND AND PURPOSE Hydrogen sulfide (H₂S) is a signalling molecule that belongs to the gasotransmitter family. Two major sources for endogenous enzymatic production of H₂S are cystathionine β synthase (CBS) and cystathionine γ lyase (CSE). In the present study, we examined the selectivity of commonly used pharmacological inhibitors of H₂S biosynthesis towards CSE and CBS. EXPERIMENTAL APP...
BACKGROUND Hydrogen sulfide (H2S) has recently been shown to play an important role in the digestive system, but the role of endogenous H2S produced locally in the gallbladder is unknown. The aim of this study was to investigate whether gallbladder possesses the enzymatic machinery to synthesize H2S, and whether H2S synthesis is changed in gallbladder inflammation during acute acalculous cholec...
AIMS Hydrogen sulfide (H2S) is a vasoactive gasotransmitter that is endogenously produced in the vasculature by the enzyme cystathionine γ-lyase (CSE). However, the importance of CSE activity and local H2S generation for ischaemic vascular remodelling remains completely unknown. In this study, we examine the hypothesis that CSE critically regulates ischaemic vascular remodelling involving H2S-d...
L-Methionine gamma-lyase (EC 4.4.1.11) is a pyridoxal 5'-phosphate-dependent multifunctional enzyme. Measuring the initial velocity of alpha-ketobutyrate production by alpha,gamma-elimination of L-methionine catalyzed by L-methionine gamma-lyase is not very feasible, because the enzyme simultaneously catalyzes both gamma-replacement and alpha,gamma-elimination. To develop an accurate enzyme ass...
