Isolation of 4'-hydroxyechinenone from Micrococcus roseus.
The carotenoid 4'-hydroxyechinenone (4'-hydroxy-beta, beta-carotene-4-one) was isolated from Micrococcus roseus. It is proposed as an intermediate between echinenone and canthaxanthin.

متن کاملIsolation and identification of echinenone from Micrococcus roseus.
An orange carotenoid from Micrococcus roseus was purified by solvent partitioning followed by column and thin-layer chromatography. Absorption spectra, chromatographic mobility, and partition coefficient suggested that the pigment was echinenone (4-keto-beta-carotene). Reduction yielded a pigment with the spectral and polar properties of isocryptoxanthin (4-hydroxy-beta-carotene), the expected ...
متن کاملIsolation and characterization of carotenoid pigments of Micrococcus roseus.
In addition to canthaxanthin, seven pigment fractions were isolated from Micrococcus roseus. They were purified by solvent partitioning and by column and thin-layer chromatography. Visible absorption spectra, chromatographic behavior, and partition coefficients of the pigments and derivatives prepared from the pigments were used in characterizing them. Both alpha- and beta-carotene derivatives ...

The peptidoglycan of bacterial cell walls is biosynthesized in a complex reaction cycle in which lipid intermediates serve as carriers of activated sugar fragments (1). The lipid intermediates (e.g., lipid-P-P-disaccharide-pentapeptide) have been identified as derivatives of an acyclic isoprenoid alcohol which has a chain length of 11 isoprene units (2, 3). In the cyclic reaction, the disacchar...
