Accepted name: S-methyl-1-thioxylulose 5-phosphate methylthiotransferase
Reaction: S-methyl-1-thio-D-xylulose 5-phosphate + glutathione = 1-deoxy-D-xylulose 5-phosphate + S-(methylsulfanyl)glutathione
Other name(s): 1-methylthioxylulose 5-phosphate sulfurylase (incorrect)
Systematic name: S-methyl-1-thio-D-xylulose 5-phosphate:glutathione methylthiotransferase
Comments: The enzyme, characterized from the bacterium Rhodospirillum rubrum, belongs to the cupin superfamily and contains a manganese ion. It participates in an anaerobic salvage pathway that restores methionine from S-methyl-5′-thioadenosine. The enzyme was assayed in vitro using L-dithiothreitol instead of glutathione.
