Summary:
2-oxopent-4-enoate is a common intermediate in the aerobic degradation of many aromatic compounds, including catechol, toluene, naphthalene and dibenzofuran.

The degradation pathway depicted here has been described in several organisms, including Escherichia coli K-12. The genes encoding the enzymes of this pathway are often found on plasmids, such as naphthalene catabolic plasmids (pWW60-22 [Platt95] and pND6-1 [Li04a]), nitrobenzene catabolic plasmids (pNB1 and pNB2, [Park00]) and toluene catabolic plasmids (TOL) such as pWW102 [Aemprapa98].

In this pathway 2-oxopent-4-enoate is hydrolyzed to 4-hydroxy-2-oxopentanoate by the enzyme 2-oxopent-4-enoate hydratase. 4-hydroxy-2-oxopentanoate is broken into pyruvate and acetaldehyde, which is then converted to acetyl-CoA by acetaldehyde dehydrogenase [Harayama89, Platt95].

Superpathways: naphthalene degradation to acetyl-CoA , mandelate degradation to acetyl-CoA , 3-phenylpropionate and 3-(3-hydroxyphenyl)propionate degradation , superpathway of aromatic compound degradation via 3-oxoadipate , superpathway of aromatic compound degradation via 2-oxopent-4-enoate , tryptophan degradation XII (Geobacillus) , catechol degradation I (meta-cleavage pathway) , catechol degradation II (meta-cleavage pathway) , tryptophan degradation IX , p-cumate degradation , p-cymene degradation , toluene degradation II (aerobic) (via 4-methylcatechol) , toluene degradation I (aerobic) (via o-cresol) , toluene degradation V (aerobic) (via toluene-cis-diol) , toluene degradation IV (aerobic) (via catechol) , meta cleavage pathway of aromatic compounds , superpathway of aerobic toluene degradation
