The function of ENSG00000175287 (PHYHD1, phytanoyl-CoA dioxygenase domain containing 1) is as follows. 2-oxoglutarate(2OG)-dependent dioxygenase that catalyzes the conversion of 2-oxoglutarate to succinate and CO(2) in an iron- dependent manner (PubMed:21530488). However, does not couple 2OG turnover to the hydroxylation of acyl-coenzyme A derivatives, implying that it is not directly involved in phytanoyl coenzyme-A metabolism (PubMed:21530488). Does not show detectable activity towards fatty acid CoA thioesters (PubMed:21530488). . [Isoform 2]: Isoform 2 probably lacks enzyme activity. . [Isoform 3]: Isoform 3 probably lacks enzyme activity. .
