Name4-hydroxyphenylacetate degradation
TypePATHWAY
Description4-hydroxyphenylacetic acid, a degradation product of tyrosine via one of several routes, of phenylalanine via phenylacetate, and of environmental DDT is metabolized in this pathway to the common metabolites succinate and pyruvate via homoprotocatechuate. 4-hydroxyphenylacetic acid may also be found in the environment and transported into the cell. The genes encoding the components of this pathway are often organized into apparent operons which include regulatory elements as well as a variety of transport systems. A number of genomes show partial evidence of the pathway based on homologs of the well-characterized enzymes from other species. Often, promising candidates for the missing steps are found in the vicinity. These are suggestive of enzymes which have been adapted from ancestral sequences having a different function. Of course, the possibility exists that it is the entire pathway that has been modified in these species and it is other structurally related compounds that are being metabolized instead of 4-hydroxyphenylacetic acid.
