Bifunctional coenzyme A synthase is an enzyme that in mammals is encoded by the COASY gene that catalyses the synthesis of coenzyme A from 4'-phosphopantetheine.[5][6][7]

Function

[edit]

COASY is an enzyme that catalyzes the last two steps in the synthesis of coenzyme A from vitamin B5 (pantothenic acid). The primary substrate is 4'-phosphopantetheine and COASY is a bifunctional enzyme in this pathway:

In mammals this is a single enzyme, but in organisms including yeast and bacteria these enzymes are encoded by separate genes.[8]

Interactions

[edit]

COASY has been shown to interact with P70-S6 Kinase 1.[9] In 2009, COASY has also been implicated in PI3K signaling, as it was shown to interact with a regulatory subunit of PI3K.[10]

Clinical significance

[edit]

Loss of function mutations to COASY have been associated with an ultra-rare disease that causes neurodegeneration with brain iron accumulation called COASY protein-associated neurodegeneration (CoPAN), or NBIA6.[8][11][12]
