3-Hydroxypropionate pathway
Encyclopedia
3-Hydroxypropionate Pathway is a CO2 assimilatory pathway observed in bacteria. Inorganic CO2 is fixed by acetyl-CoA
and propionyl-CoA
carboxylases thus forming malyl-CoA and glyoxylate. Malyl-CoA is further split into acetyl-CoA (to replenish this cycle). Researchers have demonstrated that this pathway was found only in Chloroflexus, a nonsulfur photosynthetic bacterium, however recent studies show that 3-Hydroxypropionate pathway is found in several chemotrophic archaea

Acetyl-CoA
Acetyl coenzyme A or acetyl-CoA is an important molecule in metabolism, used in many biochemical reactions. Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle to be oxidized for energy production. In chemical structure, acetyl-CoA is the thioester...

Propionyl-CoA
Propionyl-CoA is a coenzyme A derivative of propionic acid.-Production:There are several different ways in which it is formed:* It is formed as a product of beta-oxidation of odd-chain fatty acids....
