Phosphatidylglycerol (PG) in thylakoid membrane is essential for growth and photosynthesis of photosynthetic organisms. Although the sn-2 position of PG in thylakoid membrane is exclusively esterified with C16 fatty acids, the functional importance of the C16 fatty-acyl chains at the sn-2 position has not been clarified. In this study, we chem. synthesized non-metabolizable PG mols.: we introduced linoleic acid (18:2, fatty acid containing 18 carbons with 2 double bonds) and one of the saturated fatty acids with different chain length (12:0, 14:0, 16:0, 18:0 and 20:0) by ether linkage to the sn-1 and sn-2 positions, resp. With the synthesized ether-linked PG mols., we checked whether they could complement the growth and photosynthesis of pgsA mutant cells of Synechocystis sp. PCC 6803 to understand the importance of length of fatty chains at the sn-2 position of PG. The pgsA mutant is incapable of synthesizing PG, so it requires exogenous PG added to medium for growth. The growth rate and photosynthetic activity of mutant cells depended on the length of fatty chains: the PG mol. species binding 16:0 most effectively complemented the growth and photosynthesis of mutant cells, and other PG mol. species with fatty chains shorter or longer than 16:0 were less effective; especially, those binding 12:0 inhibited the growth and photosynthetic activity of the mutant cells. These data demonstrate that length of fatty chains bound to the sn-2 position of PG is critical for PG performance in growth and photosynthesis. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Product Details of 76-83-5).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Product Details of 76-83-5
