aminopropyltransferase is responsible for biosynthesis of spermidine, spermine, and multiple uncommon polyamines in osmotic stress-tolerant alfalfa.
For example, protein bait evaluation, protein cues in dry traps (ammonium acetate + putrescine
or trimethylamine), and other protein sources that may be important to flies in the field should be evaluated.
Eight biogenic amines were investigated on wines, according to standards of putrescine
(PUT) dihydrochloride, spermidine (SPD) trihydrochloride, spermine (SPM) tetrahydrochloride, agmatine (AGM) sulfate, cadaverine (CAD) dihydrochloride, serotonine (SRT) hydrochloride, histamine (HIM) dihydrochloride, tyramine (TYM), tryptamine (TRM) and 2-phenylethylamine (PHM) dihydrochloride purchased from Sigma Chemical Co.
Action of a polyamine putrescine
in genetic material of Allium cepa.
A number of growth regulators like thiourea, betaine, putrescine
, etc are used to surge the yield and growth of crops.
6 mM glucose, 100 gM putrescine
, 30 nM selenite, 20 nM progesterone (all purchased from Sigma-Aldrich), 1x GlutaMax and 1% penicillin/streptomycin (both from Gibco), 20 ng/ml epidermal growth factor (EGF) and 20 ng/ml FGF2 (both from R&D).
They adjust the materials translocation such as spermine, putrescine
and spermidine and carbon source of roots supply as muciliageneus substance to the bacteria .
Biogenic amines, such as histamine (His), cadaverine, putrescine
, spermine, and spermidine, are breakdown products that are produced during decarboxylation of amino acid catabolism.
Role of putrescine
in regulating fruit softening and antioxidative enzyme systems in 'Samar Bahisht Chaunsa' mango.
The latter is further hydrolyzed to putrescine
and urea by agmatinase, which is encoded by AGMAT gene.
Microbial growth and metabolism is a major cause of fish spoilage which produce amines, biogenic amines such as putrescine
, histamine and cadaverine, organic acids, sulphides, alcohols, aldehydes and ketones with unpleasant and unacceptable off-flavors .
The importance of human intestinal diamine oxidase in the oxidation of histamine and/or putrescine
