Function
- converts phytanoyl-CoA to 2-hydroxyphytanoyl-CoA
- lipid metabolism; fatty acid metabolism
- interacts specifically with the immunophilin FKBP52 & PHYHIP
phytanoyl-CoA + 2-oxoglutarate + O2 = 2-hydroxyphytanoyl-CoA + succinate + CO2
Structure
belongs to the phyH family
Compartment
Expression
- expressed in liver, kidney, & T-cells
- not expressed in spleen, brain, heart, lung & skeletal muscle
Pathology
- defects in PHYH are a cause of Refsum disease
