| Popis: | 1. 1. Streptococcus lactis NCDO 712 contains at least three unusually polar glycerophosphoglycolipids. One of them was composed of d -glucose, glycerol, fatty acid ester, and phosphorus in the molar ratio of approx. 2 : 3: 3 : 2. The structure was established as 1,2- di -O- acyl -3-O-[6-(sn- glycero -1- phospho -3-sn- glycero -1- phospho -α- d - glucopyranosyl - → 2)-(6-O- acyl -α- d - glucopyranosyl )]- glycerol . 2. 2. The second glycerophosphoglycolipid was shown to have the same core structure but is lacking the carbohydrate-linked fatty acid. The third glycerophosphoglycolipid is a glycosylated derivative of the first one bearing an α-galactosyl residue at position 2 of the inner glycolipid-linked glycerophosphate moiety. 3. 3. These novel phosphoglycolipids are considered to be the so far missing link between simple glycerophosphoglycolipids and lipoteichoic acids of Grampositive bacteria. |
