A cDNA encoding S-adenosyl-L-methionine synthetase from poplar.
Adomet synthetase (EC 2.5.1.6) catalyzes the formation of Adomet, which serves as a methyl group donor in highly specific transmethylation reactions involving a11 kinds of acceptor molecules such as proteins, nucleic acids, phenylpropanoid derivatives, polysaccharides, cyclic fatty acids, etc. Adomet also plays a role in amino acid biosynthesis and polyamine biosynthesis. In plants, Adomet has ...
متن کاملCloning and nucleotide sequence of a cDNA encoding S-adenosyl-L-methionine synthetase from mustard (Brassica juncea [L.] Czern & Coss).
Ethylene, a gaseous hormone in plants, is involved in the regulation of a wide range of plant physiological processes, including leaf abscission, fruit ripening, and flower senescence (Yang and Hoffman, 1984). SAM or Adomet synthetase (ATP:L-methionine S-adenosyltransferase; EC 2.5.1.6) catalyzes the conversion of Met to SAM in the presence of ATP and Mg2+, which is the first step in ethylene b...
متن کاملInterleukin-2 induces gamma-S-adenosyl-L-methionine synthetase gene expression during T-lymphocyte activation.
The regulation of expression of the gamma-S-adenosyl-L-methionine (AdoMet) synthetase gene was investigated in T-cells during G0/G1 transition, as well as throughout the G1 phase. Stimulation of G0 T-lymphocytes with concanavalin A induces AdoMet synthetase gene expression, starting 8 h after stimulation. Interleukin-2 (IL-2) stimulates the induction of this gene expression and AdoMet synthetas...
متن کاملConferred Synthetase Promoter of Arabidopsisby the S - Adenosyl - L - Methionine thaliana in Transgenic Poplar
adenosyl-L-methionine synthetase (SAM-S) Psam-1 confers expression preferentially in the yascular tissue. In search for promoters that driye expression in particular ce]ls of the lignifying tisslles i" trees, we haye analyzed the expression pattern conferred by the Psam-1 promoter in transgenic pop]ar. Histochemica] analyses demonstrated fi glucuronidase (GUS} actiyity mainly in phloem and cort...
متن کاملPurification of rat liver S-adenosyl-L-methionine decarboxylase.
The amount of S-adenosyl-l-methionine decarboxylase present in rat liver was enhanced 17-fold by administration of methylglyoxal bis(guanylhydrazone),* a specific inhibitor of the enzyme. The enzyme was purified 1400-fold in 50% yield from such liver extracts by chromatography on columns of the inhibitor bound to Sepharose. The purified enzyme had no spermidine synthetase activity.
