Protein
Long-chain-fatty-acid--AMP ligase FadD26
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Function
Catalyzes the activation of long-chain fatty acids (C22-24 fatty acids) as acyl-adenylates (acyl-AMP), which are then transferred to the multifunctional polyketide synthase PpsA for further chain extension. Involved in the biosynthesis of phthiocerol dimycocerosate (DIM A) and phthiodiolone dimycocerosate (DIM B) (By similarity).
Similarity
Belongs to the ATP-dependent AMP-binding enzyme family.
