Herbivore-induced SABATH methyltransferases of maize that methylate anthranilic acid using s-adenosyl-L-methionine.
Volatile methyl esters are common constituents of plant volatiles with important functions in plant defense. To study the biosynthesis of these compounds, especially methyl anthranilate and methyl salicylate, we identified a group of methyltransferases that are members of the SABATH enzyme family in maize (Zea mays). In vitro biochemical characterization after bacterial expression revealed thre...
متن کاملThe enzymatic decomposition of S-adenosyl-L-methionine.
The role of S-adenosyl-n-methionine as a methyl donor has been investigated in mammalian systems (1) and in microbial metabolism (2-4). In addition, the compound is involved in the formation of spermidine from putrescine (5). Information concerning the stability of S-adenosylmethionine in various enzymatic systems is a necessary prerequisite for studies concerning its role in group transfer. In...
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.
متن کاملA 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 کاملBiosynthesis of mycophenolic acid: purification and characterization of S-adenosyl-L-methionine: demethylmycophenolic acid O-methyltransferase.
The final step in the biosynthesis of mycophenolic acid involves the transfer of a methyl group from S-adenosylmethionine to demethylmycophenolic acid. The enzyme, S-adenosylmethionine:demethylmycophenolic acid O-methyltransferase, was isolated from Penicillium stoloniferum and purified 2,700-fold by ammonium sulfate fractionation and diethylaminoethyl-cellulose and Sephadex G-200 chromatograph...
