A DIETHER ANALOG OF PHOSPHATIDYL GLYCEROPHOSPHATE IN HALOBACTERIUM CUTIRUBRUM,
Abstract
The major phosphatide in the extremely halophilic bacterium, Halobacterium cutirubrum, was isolated by a combination of solvent fractionation, precipitation through the barium salt, and final purification as the sodium salt. Analytical and degradative data showed the phosphatide to be a phosphatidyl glycerophosphate with two long-chain ether groups instead of fatty acid ester groups. Both long-chain groups were found to be identical and were shown by comparison of infrared, nuclear magnetic resonance, and mass spectra with those of dihydrophytyl derivatives to have the structure 3,7,11,15-tetramethylhexadecyl. The two long-chain groups are joined by ether linkages to the alpha, beta-positions of L-glycerol. Possible biochemical and physiological functions of this unusual phosphatide in the halophile cell are discussed. (Author)
