摘要: Bacteria are genetically engineered to produce 3-hyrdoxypropionate (3-HP). The bacteria carboxydotrophic acetogens. acetyl-coA using the Wood-Ljungdahl pathway for fixing CO/C0?2#191. A malonyl-coA reductase from a bacterium that contains such an enzyme is introduced. Additionally, carboxylase may also be introduced production of 3-HP can improved by overproduction acetyl-CoA or biotin. This effected promoters higher copy number enzymes catalytically more efficient.
