Biosynthesis of Nucleic Acids in Bacillus megaterium
So-called 'chromatin b)odies' have been observed in whole cells, protoplasts and spores of Bacillus megaterium by cytological and electron-microscopical techniques (Fitzjames, 1953, 1958; Robinow, 1956). In ultra-thin sections of whole cells the chromatin body appears as an area less electron-dense than the surrounding cytoplasm and made up of a network of fine fibrils with no bounding membrane...
متن کاملSalt-inducible bionylon polymer from Bacillus megaterium.
Poly-gamma-glutamate (PGA) is a chiral polyamide material that possesses a nylon-like backbone, a bionylon polymer. We examined the PGA productivity of Bacillus megaterium and found NaCl-responsive PGA production in the bacterium. In the system of B. megaterium, salt would be significant in controlling the yield, molecular size, and stereochemistry of bionylon.
متن کاملPlasmolysis in Bacillus Megaterium.
Weibull, Claes (Central Bacteriological Laboratory of Stockholm City, Stockholm, Sweden). Plasmolysis in Bacillus megaterium. J. Bacteriol. 89:1151-1154. 1965.-Sucrose solutions stronger than 1 m caused plasmolysis in Bacillus megaterium strain M, whereas concentrated NaCl and KNO(3) solutions were ineffective. In plasmolyzed cells, mesosome bodies were found in pockets between the cytoplasmic ...
متن کاملEpoxidation of unsaturated fatty acids by a soluble cytochrome P-450-dependent system from Bacillus megaterium.
In previous publications from this laboratory we have described a soluble, partially purified cytochrome P-450-dependent monooxygenase complex that, in the presence of NADPH and O2, catalyzes the monohydroxylation of long chain fatty acids, alcohols, and amides at the omega -1, omega -2, and omega -3 positions. We have now found that this preparation catalyzes the epoxidation as well as the hyd...
متن کاملSelective hydroxylation of highly branched fatty acids and their derivatives by CYP102A1 from Bacillus megaterium.
Highly branched fatty acids, the main components of the preen-gland waxes of the domestic goose and the Muscovy duck, and their derivatives are promising chiral precursors for the synthesis of macrolide antibiotics. The key step in the utilisation of these compounds is their regioselective hydroxylation, which cannot be achieved in a classical chemical approach. Three P450 monooxygenases, CYP10...
