Research into detailed aspects of the phytanoyl-CoA dioxygenase containing 1 isoform a revealed its role in the alpha-oxidation of phytanoyl-CoA, a metabolite of phytanic acid. Phytanic acid is a long-chain fatty acid that requires alpha-oxidation, before entrance into the beta-oxidation pathway, due to a methyl group on the third carbon. Through evolutionary sequence analysis it was shown that PhyD is most conserved in animals and fungi most likely due to them requiring it to break down the fatty acids they consume, whilst high conservation was not required by plants. The defined active site was discovered to a cleft in the molecule containing Fe2+ binding sites and a 2-oxoglyterate binding site. This structure is extremely comparable to the phytanoyl-CoA hydroxylase indicating possible analogous functions. When compared to the other isoforms there is highest similarity to isoform b which shares the cleft shape in its structure, whilst isoform c is most far removed due to a change in reading frame. The investigation of the molecular mechanics of PhyD show that mutations to this gene can cause Refsum's disease (RD) due to the build up of phytanic acid, thus a greater knowledge of its action may play a vital role in treatment, recognition and prevention of this disorder.
