Polyamine metabolism in the Microsporidia.
Members of the phylum Microspora are all obligate intracellular parasites. Little is known concerning metabolic pathways in these parasites, some of which pose serious problems in immunocompromised patients. We investigated polyamine metabolism in the systemic pathogen Enterocytozoon cuniculi using intact pre-emergent spores, and cell-free preparations. We found both polyamine synthetic and int...
متن کاملStress and Polyamine Metabolism
The polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) (Fig. 1) have been shown to be involved in a variety of plant growth and developmental processes, including cell division, vascular differentiation, root initiation, shoot formation, flower initiation and development, fruit ripening and senescence and embryoid formation in tissue cultures (Evans and Malmberg, 1989; Galst...

Polyamines are ubiquitous organic cations of low molecular weight. The content of these amines is closely regulated by the cell according to the state of growth. The reactions responsible for the biosynthesis and interconversion of the polyamines and their precursor putrescine are described and the means by which polyamine content can be varied in response to exogenous stimuli are discussed. Th...
متن کاملPolyamine metabolism and virus replication.
It has become apparent during the past two decades that the vital functions of eukaryotic cells are intimately associated with the synthesis of the polyamines, spermidine and spermine (Pegg & McCann, 1982). Many studies using either whole animals or cell cultures have shown marked increases in ornithine decarboxylase (EC 4.1.1.17) in growing organs and tissues which leads to the formation of pu...
