描述
Cis-4-hydroxycyclohexylacetic acid is a tyrosine metabolite that has been found in the urine of a patient with a defect of 4-hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27), an inborn error of metabolism. (PMIDs 701419, 719903)
4-Hydroxyphenylpyruvate dioxygenase participates in the tyrosine catabolic pathway by catalyzing the conversion of 4-hydroxyphenylpyruvate to homogentisate (Hager et al., 1957). The mechanism of action of 4-hydroxyphenylpyruvate dioxygenase involves a decarboxylation step and an oxidation step, followed by a rearrangement step to form homogentisic acid (Tomoeda et al., 2000).
Awata et al. (1994) determined that the HPD gene contains 14 exons. Analysis of the 5-prime flanking sequence of the gene suggested that expression of the gene is regulated by hepatocyte-specific and liver-enriched transcription factors, as well as by hormones.
