Lipid-related proteins identified in the purified lipid
droplets in C. reinhardtii include acyl activating enzymes,
lipases, lipid trafficking proteins, acyltransferases of the
Kennedy pathway [i.e., a glycerol-3-phosphate acyltransferase
(GPAT), a lysophosphatidic acid acyltransferase
(LPAT)], enzymes of the transacylation pathway [the
phospholipid:diacylglycerol acyltransferase (PDAT) and
two lysophosphatidyl lipid acyltransferases (LPLAT)], and
also membrane lipid synthesizing enzymes, for example, the
betaine lipid synthase (BTA1) responsible for synthesis of
DGTS
