      <name>Phenylalanine metabolism</name>
      <description>The pathways of the metabolism of phenylalaline begins with the conversion of chorismate to prephenate through a P-protein (chorismate mutase:pheA). 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.</description>

      <name>2-Oxopent-4-enoate metabolism</name>
      <description>The pathway starts with trans-cinnamate interacting with a hydrogen ion, an oxygen molecule, and a NADH through a cinnamate dioxygenase resulting in a NAD and a cis-3-(3-Carboxyethenyl)-3,5-cyclohexadiene-1,2-diol which then interact together through a  2,3-dihydroxy-2,3-dihydrophenylpropionate dehydrogenase resulting in the release of a hydrogen ion, an NADH molecule and a 2,3 dihydroxy-trans-cinnamate.

The second way by which the 2,3 dihydroxy-trans-cinnamate is acquired is through a 3-hydroxy-trans-cinnamate interacting with a hydrogen ion, a NADH and an oxygen molecule through a 3-(3-hydroxyphenyl)propionate 2-hydroxylase resulting in the release of a NAD molecule, a water molecule and a 2,3-dihydroxy-trans-cinnamate.

The compound 2,3 dihydroxy-trans-cinnamate then interacts with an oxygen molecule through a 2,3-dihydroxyphenylpropionate 1,2-dioxygenase resulting in a hydrogen ion and a 2-hydroxy-6-oxonona-2,4,7-triene-1,9-dioate. The latter compound then interacts with a water molecule through a 2-hydroxy-6-oxononatrienedioate hydrolase resulting in a release of a hydrogen ion, a fumarate molecule and (2Z)-2-hydroxypenta-2,4-dienoate. The latter compound reacts spontaneously to isomerize into a 2-oxopent-4-enoate. This compound is then hydrated through a 2-oxopent-4-enoate hydratase resulting in a 4-hydroxy-2-oxopentanoate. This compound then interacts with a 4-hydroxy-2-ketovalerate aldolase resulting in the release of a pyruvate, and an acetaldehyde. The acetaldehyde then interacts with a coenzyme A and a NAD molecule through a acetaldehyde dehydrogenase resulting in a hydrogen ion, a NADH and an acetyl-coa which can be incorporated into the TCA cycle</description>
