Members of this family are found in 3-mercaptopyruvate sulfurtransferase, and have no known function. They adopt a structure consisting of a four-stranded antiparallel beta-sheet and an alpha-helix, arranged in a beta(2)-alpha-beta(2) fashion, and bearing a remarkable structural similarity to the FK506-binding protein class of peptidylprolyl cis/trans-isomerase [1].

A	3-mercaptopyruvate sulfurtransferase M-CSA #871	Sulfurtransferases (EC 2.8.1.1–5) catalyze the transfer of sulfane sulfur from a donor molecule to a thiophilic acceptor. These enzymes are widely distributed in plants, animals, and bacteria and have been implicated in a wide range of biological processes. The archetypal sulfurtransferase is rhodanese, a thiosulfate: cyanide sulfurtransferase (TST) able to catalyse the transfer of the thiosulfate sulfur to cyanide in vitro. The related 3-mercaptopyruvate sulfurtransferase (3-mercaptopyruvate:cyanide sulfurtransferase (MST)), first discovered in rat liver, catalyses reactions similar to those catalysed by rhodanese, but uses 3-mercaptopyruvate in preference to thiosulfate as the donor in the two-step reaction.
