up | growth on ethylamide induces the enzyme, the ethylmalonyl-CoA mutase activity increases to a level sufficient for the observed growth rate at 9 h, which correlates with an upregulation of RNA transcripts for ecm and a decrease in the levels of ethylmalonyl-CoA | Methylorubrum extorquens |

malfunction | overexpression of gene ecm removes control in the ethylmalonyl-CoA pathway | Methylorubrum extorquens |
metabolism | the metabolism of one- and two-carbon compounds by the methylotrophic bacterium Methylobacterium extorquens AM1 involves high carbon flux through the ethylmalonyl-CoA pathway (EMC pathway), metabolic pathway for two carbon metabolism, overview. During growth on ethylamine, the EMC pathway operates as a linear pathway carrying the full assimilatory flux to produce glyoxylate, malate, and succinate, metabolite profiles. Assimilatory carbon enters the ethylmalonyl-CoA pathway directly as acetyl-CoA, bypassing pathways for formaldehyde oxidation/assimilation and the regulatory mechanisms controlling them | Methylorubrum extorquens |
physiological function | the ethylmalonyl-CoA pathway, ethylmalonyl-CoA mutase is a metabolic control point to restrict the production of glyoxylate | Methylorubrum extorquens |
