KEGG ENZYME: 1.14.14.177

ENZYME: 1.14.14.177

Entry

EC 1.14.14.177              Enzyme

Name

ultra-long-chain fatty acid omega-hydroxylase;
CYP4F22 (gene name)

Class

Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor

Sysname

ultra-long-chain fatty acid,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (omega-hydroxylating)

Reaction(IUBMB)

an ultra-long-chain fatty acid + [reduced NADPH---hemoprotein reductase] + O2 = an ultra-long-chain omega-hydroxy fatty acid + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R12714]

Reaction(KEGG)

R12714;
(other) R01348

Substrate

ultra-long-chain fatty acid [CPD:C22352];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007]

Product

ultra-long-chain omega-hydroxy fatty acid [CPD:C22353];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001]

Comment

The enzyme, which is expressed in the epidermis of mammals, catalyses the omega-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.
