EC 1.14.14.177 Details
show Brenda entryEC number
1.14.14.177
Accepted name
ultra-long-chain fatty acid ω-hydroxylase
Reaction
an ultra-long-chain fatty acid + [reduced NADPH—hemoprotein reductase] + O2 = an ultra-long-chain ω-hydroxy fatty acid + [oxidized NADPH—hemoprotein reductase] + H2O
Other name(s)
CYP4F22 (gene name)
Systematic name
ultra-long-chain fatty acid,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (ω-hydroxylating)
Comment
The enzyme, which is expressed in the epidermis of mammals, catalyses the ω-hydroxylation of ultra-long-chain fatty acids (C28 to C36). The products are incorporated into acylceramides, epidermis-specific ceramide species that are very important for skin barrier formation.
