| - | + | The 3-Hydroxypropionate bicycle, also known as the 3-Hydroxypropionate pathway, is a process that allows some bacteria to generate 3-Hydroxypropionate utilizing carbon dioxide. In this pathway CO2 is fixed (''i.e.'' incorporated) by the action of two enzymes, [[acetyl-CoA carboxylase]] and [[propionyl-CoA carboxylase]]. See also [[Carbon Fixation]]. | |

| - | = | + | These enzymes generate <scene name='49/492046/Cv/7'>malonyl-CoA</scene> and <scene name='95/950327/Cv/1'>(S)-methylmalonyl-CoA</scene>, respectively. Malonyl-CoA, in a series of reactions is further split into <scene name='43/430893/Cv/2'>acetyl-CoA</scene> and <scene name='93/939250/Cv/1'>glyoxylate</scene>. Glyoxylate is incorporated into beta-methylmalyl-CoA which is then split, again through a series of reactions to release pyruvate as well as acetate, which is used to replenish the cycle. |
