ID 4.4.1.34 DE isoprene-epoxide--glutathione S-transferase. CA 2-glutathionyl-2-methylbut-3-en-1-ol = (3R)-3,4-epoxy-3-methylbut-1-ene + CA glutathione. CC -!- The enzyme, characterized from the bacterium Rhodococcus sp. AD45, CC is involved in isoprene degradation. CC -!- The enzyme can catalyze the glutathione-dependent ring opening of CC various epoxides, but the highest activity is with (3R)-3,4-epoxy-3- CC methylbut-1-ene, which is derived from isoprene by EC 1.14.13.69.
