DescriptionPC(16:0/16:0) is a phosphatidylchloline (PC). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylcholines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PC(16:0/16:0), in particular, consists of two hexadecanoyl chains at positions C-1 and C-2. In E. coli, PCs can be found in the integral component of the cell outer membrane. They are hydrolyzed by Phospholipases to a 2-acylglycerophosphocholine and a carboxylate.

Enzymes

General function:
Involved in phosphotransferase activity, for other substituted phosphate groups
Specific function:
Involved in protein-dependent process of phospholipid transport to distribute phosphatidyl choline to the lumenal surface. The multiple transmembrane domains and lumenal hydrophilic domains of the cholinephosphotransferase might participate in the transport process

Reactions
CDP-choline + 1,2-diacylglycerol → CMP + a phosphatidylcholine.
General function:
Involved in N-methyltransferase activity
Specific function:
S-adenosyl-L-methionine + phospholipid olefinic fatty acid = S-adenosyl-L-homocysteine + phospholipid methylene fatty acid

Reactions
S-adenosyl-L-methionine + phospholipid olefinic fatty acid → S-adenosyl-L-homocysteine + phospholipid methylene fatty acid.
General function:
Involved in protein binding
Specific function:
Required for meiosis and spore formation. Seems to be involved in the coordinate induction of late meiotic events. PLD activity is induced under sporulation conditions and seems to be necessary to complete the meiotic cycle, but not for vegetative cell growth

Specific function:
Intracellular phospholipase B that catalyzes the double deacylation of phosphatidylcholine (PC) to glycerophosphocholine (GroPCho). Plays an important role in membrane lipid homeostasis. Responsible for the rapid PC turnover in response to inositol, elevated temperatures, or when choline is present in the growth medium
