Abstract
Organomercurial lyase (MerB) catalyzes the difficult cleavage of C-Hg bonds to hydrocarbon and mercuric dithiol products. Model compounds providing two or three thiolate ligands activate organomercurials toward acidic cleavage under mild conditions, which supports a mechanism in which MerB enzymes use two conserved active-site cysteines to activate the substrate.
