It is shown that H2S is physiologically generated by cystathionine γ-lyase (CSE) and that genetic deletion of this enzyme in mice markedly reduces H 2S levels in the serum, heart, aorta, and other tissues.

Ex vivo endogenous H2S physiologically modifies cysteine residues in many proteins, including glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and actin, converting Cysteine -SH groups to -SSH groups in a process the authors call S-sulfhydration.
Carbon Monoxide: Endogenous Production, Physiological Functions, and Pharmacological Applications

H2S is a major EDHF that causes vascular endothelial and smooth muscle cell hyperpolarization and vasorelaxation by activating the ATP-sensitive, intermediate conductance and small conductance potassium channels through cysteine S-sulfhydration.

Investigation of the role of exogenous and endogenous hydrogen sulfide on neovascularization and wound healing in vitro and in vivo concludes that endogenous and exogenous H2S stimulates EC-related angiogenic properties through a KATP channel/MAPK pathway.
Hydrogen sulfide protects against cellular senescence via S-sulfhydration of Keap1 and activation of Nrf2.

These results provide a mechanistic insight into how H2S signaling mediates cellular senescence induced by oxidative stress and protects against cellular aging via S-sulfhydration of Keap1 and Nrf2 activation in association with oxidative stress.
H2S Protects Against Pressure Overload–Induced Heart Failure via Upregulation of Endothelial Nitric Oxide Synthase

H2S levels are decreased in mice in the setting of heart failure, and oral H2S therapy prevents the transition from compensated to decompensated heart failure in part via upregulation of endothelial nitric oxide synthase and increased Nitric oxide bioavailability.
