ID 2.8.4.6 DE S-methyl-1-thioxylulose 5-phosphate methylthiotransferase. AN 1-methylthioxylulose 5-phosphate sulfurylase. CA glutathione + S-methyl-1-thio-D-xylulose 5-phosphate = 1-deoxy-D-xylulose CA 5-phosphate + S-(methylsulfanyl)glutathione. CC -!- The enzyme, characterized from the bacterium Rhodospirillum rubrum, CC belongs to the cupin superfamily and contains a manganese ion. CC -!- It participates in an anaerobic salvage pathway that restores CC methionine from S-methyl-5'-thioadenosine. CC -!- The enzyme was assayed in vitro using L-dithiothreitol instead of CC glutathione. DR Q2RSU5, CUPIN_RHORT; //
