| + | == Function == | ||
| + | '''Methylcitrate synthase''' (MCS) participates in propanoate metabolism. It catalyzes the conversion of acyl to alkyl group in the reaction which converts propanoyl-CoA and oxaloacetate to 2-hydroxybutane-1,2,3-tricarboxylate and CoA<ref>PMID:10482501</ref>. The metabolism of propionyl-CoA in microorganism is performed by the methylcitrate cycle. The methylcitrate cycle contains MCS, methylcitrate dehydrogenase and methylisocitrate lyase<ref>PMID:18048912</ref>. The methylcitrate cycle can serve as a carbon and energy source of growth. In the presence of glucose, the cycle serves to remove the toxic propionate. | ||
