ENZYME entry: EC 2.8.4.6

Accepted Name
S-methyl-1-thioxylulose 5-phosphate methylthiotransferase.
Alternative Name(s)
1-methylthioxylulose 5-phosphate sulfurylase.
Reaction catalysed
glutathione + S-methyl-1-thio-D-xylulose 5-phosphate <=> 1-deoxy-D-xylulose 5-phosphate + S-(methylsulfanyl)glutathione
Comment(s)
  • 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.
