Metabolism of polyamines by Staphylococcus.
Rosenthal, Sanford M. (National Institute of Arthritis and Metabolic Diseases, Bethesda, Md.) and Donald T. Dubin. Metabolism of polyamines by Staphylococcus. J. Bacteriol. 84:859-863. 1962-Although spermine and spermidine are not detectable in staphylococci grown in purified medium, considerable amounts (0.7 to 1.4 mumole/g wet wt) were demonstrated in cells grown in the presence of these amin...
متن کاملTransgenic manipulation of the metabolism of polyamines in poplar cells.
The metabolism of polyamines (putrescine, spermidine, and spermine) has become the target of genetic manipulation because of their significance in plant development and possibly stress tolerance. We studied the polyamine metabolism in non-transgenic (NT) and transgenic cells of poplar (Populus nigra x maximowiczii) expressing a mouse Orn decarboxylase (odc) cDNA. The transgenic cells showed ele...
متن کاملGenetic manipulation of the metabolism of polyamines in poplar cells. The regulation of putrescine catabolism.
We investigated the catabolism of putrescine (Put) in a non-transgenic (NT) and a transgenic cell line of poplar (Populus nigra x maximowiczii) expressing a mouse (Mus musculus) ornithine (Orn) decarboxylase (odc) cDNA. The transgenic cells produce 3- to 4-fold higher amounts of Put than the NT cells. The rate of loss of Put from the cells and the initial half-life of cellular Put were determin...
متن کاملRegulation of Bone Metabolism
Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...
متن کاملMetabolism of polyamines in transgenic cells of carrot expressing a mouse ornithine decarboxylase cDNA.
The metabolisms of arginine (Arg), ornithine (Orn), and putrescine were compared in a nontransgenic and a transgenic cell line of carrot (Daucus carota L.) expressing a mouse Orn decarboxylase cDNA. [14C]Arg, [14C]Orn, and [14C]putrescine were fed to cells and their rates of decarboxylation, uptake, metabolism into polyamines, and incorporation into acid-insoluble material were determined. Tran...
