Vorschrift

Pathways to 3-butene-1-ol, butadiene and 2,4-pentadienoate from malonyl-CoA and acetyl-CoA are shown in FIG. 21. In these pathways, malonyl-CoA and acetyl-CoA are joined by a thiolase to form 3-oxoglutaryl-CoA. This intermediate can then be converted to 3,5-dihydroxypentanoate by several alternate routes (Steps B/C/D, Steps B/G, Steps H/I/J, Steps H/L/D, K/J). Once formed, 3,5-dihydroxypentanoate can be decarboxylated by a 3-hydroxyacid decarboxylase to form 3-butene-1-ol (Step M). Subsequent dehydration by a 3-butene-1-ol dehydrogenase or a chemical catalyst yields butadiene (Step O). Alternately, 3,5-dihydroxypentanoate can be dehydrated to 5-hydroxypent-2-enoate as shown in Step E. This intermediate can then be decarboxylated to 3-butene-1-ol (Step N) or further dehydrated to 2,4-pentadienoate (Step F).
