Protein
Phthiocerol/phthiodiolone dimycocerosyl transferase
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Function
Catalyzes diesterification of phthiocerol, phthiodiolone, and phenolphthiocerol with mycocerosic acids, the final step in the phthiocerol, phthiodiolone and phenolphthiocerol dimycocerosate esters (PDIM) synthesis. Can directly transfer the mycocerosate bound to the mycocerosic acid synthase (mas) onto the substrate alcohols. Is also able to catalyze acyl transfer using various nucleophiles as acceptors and several acyl-CoA thioesters as donors in vitro; preference is observed for saturated medium chain alcohols and long chain acyl-CoA thioesters.
Similarity
Belongs to the acyltransferase PapA5 family.
