Self-S-sulfonation in a bacterial persulfide dioxygenase mediates thiol persulfide detoxification

Julius O. Campeciño, Sofia Soares Costa, Inês D. S. Pires…·David P. Giedroc

This paper identifies a self-S-sulfonation mechanism in bacterial persulfide dioxygenase CstB that converts thiol persulfides to thiosulfate without sulfite release.
