At appropriate concentrations, hydrogen sulfide, a well-known gasotransmitter,
plays important roles in both physiology and pathophysiology. Increasing evidence
suggests that modifying thiol groups of specific cysteines in target proteins via
sulfhydration or persulfidation is one of the important mechanisms responsible
for the biological functions of hydrogen sulfide. A variety of key proteins of
different cellular pathways in mammals have been reported to be sulfhydrated by
hydrogen sulfide to participate and regulate the processes of cell
survival/death, cell differentiation, cell proliferation/hypertrophy, cellular
metabolism, mitochondrial bioenergetics/biogenesis, endoplasmic reticulum stress,
vasorelaxtion, inflammation, oxidative stress, etc. Moreover, S-sulfhydration
also exerts many biological functions through the cross-talk with other
post-translational modifications including phosphorylation, S-nitrosylation and
tyrosine nitration. This review summarizes recent studies of hydrogen
sulfide-induced sulfhydration as a posttranslational modification, an important
biological function of hydrogen sulfide, and sulfhydrated proteins are
introduced. Additionally, we discuss the main methods of detecting sulfhydration
of proteins.
