It is also known as 2-phenylethylamine, and is an alkaloid and monoamine. Phenethylamine also has a constitutional isomer 1-phenylethylamine. (HMDB) In E. coli phenylalanine metabolism, 2-phenylethylamine can be degraded to phenylacetaldehyde in a reversible reaction catalyzed by a primary-amine oxidase (EC:1.4.3.21).

Prephenate then interacts with a hydrogen ion through the same previous enzyme resulting in a release of carbon dioxide, water and a phenolpyruvic acid. Three enzymes those enconde by tyrB, aspC and ilvE are involved in catalyzing the third step of these pathways, all three can contribute to the synthesis of phenylalanine: only tyrB and aspC contribute to biosynthesis of tyrosine. Phenolpyruvic acid can also be obtained from a reversivle reaction with ammonia, a reduced acceptor and a D-amino acid dehydrogenase, resulting in a water, an acceptor and a D-phenylalanine, which can be then transported into the periplasmic space by aromatic amino acid exporter. L-phenylalanine also interacts in two reversible reactions, one involved with oxygen through a catalase peroxidase resulting in a carbon dioxide and 2-phenylacetamide. The other reaction involved an interaction with oxygen through a phenylalanine aminotransferase resulting in a oxoglutaric acid and phenylpyruvic acid. L-phenylalanine can be imported into the cytoplasm through an aromatic amino acid:H+ symporter AroP. The compound can also be imported into the periplasmic space through a transporter: L-amino acid efflux transporter. PW000921 ec00360 Metabolic Phenylethylamine metabolism The process of phenylethylamine metabolism starts with 2-phenylethylamine interacting with an oxygen molecule and a water molecule in the periplasmic space through a phenylethylamine oxidase. This reaction results in the release of a hydrogen peroxide, ammonium and phenylacetaldehyde. Phenylacetaldehyde is introduced into the cytosol and degraded into phenylacetate by reaction with a phenylacetaldehyde dehydrogenase. This reaction involves phenylacetaldehyde interacting with NAD, and a water molecule and then resulting in the release of NADH, and 2 hydrogen ion. Phenylacetate is then degraded. The first step involves phenylacetate interacting with an coenzyme A and an ATP driven phenylacetate-CoA ligase resulting in the release of a AMP, a diphosphate and a phenylacetyl-CoA. This resulting compound the interacts with a hydrogen ion, NADPH, and oxygen molecule through a ring 1,2-phenylacetyl-CoA epoxidase protein complex resulting in the release of a water molecule, an NADP and a 2-(1,2-epoxy-1,2-dihydrophenyl)acetyl-CoA. This compound is then metabolized by a ring 1,2 epoxyphenylacetyl-CoA isomerase resulting in a 2-oxepin-2(3H)-ylideneacetyl-CoA. This compound is then hydrolated through a oxepin-CoA hydrolase resulting in a 3-oxo-5,6-didehydrosuberyl-CoA semialdehyde. This commpound then interacts with a water molecule and NADP driven 3-oxo-5,6-dehydrosuberyl-CoA semialadehyde dehydrogenase resulting in 2 hydrogen ions, a NADPH and a 3-oxo-5,6-didehydrosuberyl-CoA. The resulting compound interacts with a coenzyme A and a 3-oxo-5,6 dehydrosuberyl-CoA thiolase resulting in an acetyl-CoA and a 2,3-didehydroadipyl-CoA. This resulting compound is the hydrated by a 2,3-dehydroadipyl-CoA hydratas resulting in a 3-hydroxyadipyl-CoA whuch is dehydrogenated through an NAD driven 3-hydroxyadipyl-CoA dehydrogenase resulting in a NADH, a hydrogen ion and a 3-oxoadipyl-CoA. The latter compound then interacts with conezyme A through a beta-ketoadipyl-CoA thiolase resulting in an acetyl-CoA and a succinyl-CoA. The succinyl-CoA is then integrated into the TCA cycle.
