The DGAT enzymes that catalyze the

The DGAT enzymes that catalyze the final committed step of TAG synthesis are integral membrane proteins that reside in the ER. It is responsible to transfer an acyl group from acyl-coenzyme-A to the sn-3 position of DAG in order to form TAG (Fig. 3). This enzyme has been proposed to be the rate limiting enzyme for TAG production in eukaryotes.
