  <description>Propionyl-CoA is an intermediate in the metabolism of propanoate. Propionyl-CoA is a substrate for acetyl-CoA synthetase, propionyl-CoA synthetase and 2-methylcitrate synthase. It is also involved in beta-alanine metabolism, Valine, leucine abd isoleucine degradation and C5-branched dibasic acid metabolism pathways.</description>

      <name>beta-Alanine metabolism</name>
      <description>The Beta-Alanine Metabolism starts with a product of Aspartate metabolism. Aspartate is decarboxylated by aspartate 1-decarboxylase, releasing carbon dioxide and Beta-alanine. Beta alanine is then metabolized through  a pantothenate synthetase resulting in Pantothenic acid undergoes phosphorylation through a ATP driven pantothenate kinase, resulting in D-4-phosphopantothenate.
Pantothenate (vitamin B5) is the universal precursor for the synthesis of the 4'-phosphopantetheine moiety of coenzyme A and acyl carrier protein. Only plants and microorganismscan synthesize pantothenate de novo - animals require a dietary supplement. The enzymes of this pathway are therefore considered to be antimicrobial drug targets.</description>

      <description>
Starting from L-threonine, this compound is deaminated through a threonine deaminase resulting in a hydrogen ion, a water molecule and a (2z)-2-aminobut-2-enoate. The latter compound then isomerizes to a 2-iminobutanoate, This compound then reacts spontaneously with hydrogen ion and a water molecule resulting in a ammonium and a 2-Ketobutyric acid. The latter compound interacts with CoA through a pyruvate formate-lyase / 2-ketobutyrate formate-lyase resulting in a formic acid and a propionyl-CoA. 
Propionyl-CoA can then be processed either into a 2-methylcitric acid or into a propanoyl phosphate.
Propionyl-CoA interacts with oxalacetic acid and a water molecule through a 2-methylcitrate synthase resulting in a hydrogen ion, a CoA and a 2-Methylcitric acid.The latter compound is dehydrated through a 2-methylcitrate dehydratase resulting in a water molecule and cis-2-methylaconitate. The latter compound is then dehydrated by a 
bifunctional aconitate hydratase 2 and 2-methylisocitrate dehydratase  resulting in a water molecule and methylisocitric acid. The latter compound is then processed by 2-methylisocitrate lyase resulting in a release of succinic acid and pyruvic acid.
Succinic acid can then interact with a propionyl-CoA through a propionyl-CoA:succinate CoA transferase resulting in a propionic acid and a succinyl CoA. Succinyl-CoA is then isomerized through a methylmalonyl-CoA mutase resulting in a methylmalonyl-CoA. This compound is then decarboxylated through a methylmalonyl-CoA decarboxylase resulting in a release of Carbon dioxide and Propionyl-CoA.
ropionyl-CoA interacts with a phosphate through a phosphate acetyltransferase / phosphate propionyltransferase resulting in a CoA and a propanoyl phosphate.
Propionyl-CoA can react with a phosphate through a phosphate acetyltransferase / phosphate propionyltransferase resulting in a CoA and a propanoyl phosphate. The latter compound is then dephosphorylated through a ADP driven acetate kinase/propionate kinase protein complex resulting in an ATP and Propionic acid.
Propionic acid can be processed by a reaction with CoA through a ATP-driven propionyl-CoA synthetase resulting in a pyrophosphate, an AMP and a propionyl-CoA.</description>

      <description>Based on the biochemical functions of a set of enzymes encoded within an operon, the existence of this pathway, resulting in net decarboxylation of succinate to propionate, has been proposed. However, no metabolic role for this pathway was shown. (EcoCyc)</description>

      <name>propanoyl CoA degradation</name>
      <description>The degradation of propanoyl-CoA starts with propanoyl-CoA undergoing a decarboxylase reaction by reacting with hydrogen carbonate and ATP resulting in the release of a phosphate, an ADP, a hydrogen ion and an S-methylmalonyl-CoA. This compound in turn reacts through an epimerase reaction resulting in the release of a R-methylmalonyl-CoA. This compound in turn can undergo a reversible reaction through a methylmalonyl-CoA mutase resulting in the release of a succinyl-CoA. This compound can be converted back to R-methylmalonyl-CoA through a methylmalonyl-CoA mutase. 
Methylmalonyl-CoA can then be converted into propanoyl-CoA through a methylmalonyl CoA decarboxylase . This compound in turn reacts with a succinate through a propionyl-CoA succinate CoA transferase resulting in the release of a propanoate and a succinyl-CoA.</description>
