Gamma-aminobutyric acid (4-aminobutyric acid) (GABA) and putrescine
(1,4-diaminobutane) (Put) are considered as an important compounds available in biological system .
Out of the 44 strains investigated, more than 60% of the strains were able to produce histamine, in a range of concentrations between 1.0 to 33 mg/L, and about 16% showed the additional capability to form both putrescine
Physiological responses of wheat plant to foliar treatments with arginine or putrescine
Caption: Figure 5: Transcriptional response after lethal imipenem exposure is associated with key metabolites entering the TCA pathway via increased expression of glutamate/y-aminobutyrate (GABA) catabolic pathways: transaminase pathway of putrescine
degradation (section 1, lines 1-5), glutamylated putrescine
pathway of putrescine
degradation (section 2, lines 6- 11), arginine degradation pathway to glutamate (section 3, lines 12-16), histidine degradation pathway to glutamate (section 4, lines 17-25), and glutamate flux to TCA, including the GABA shunt operon (section 5, lines 26-32).
An expressive increment in putrescine
levels was observed between day zero and day 14 in culture (Figure 2A).

(Put), spermidine (Spd), and spermine (Spm) are polyamines.
They adjust the materials translocation such as spermine, putrescine
and spermidine and carbon source of roots supply as muciliageneus substance to the bacteria .
Microbial growth and metabolism is a major cause of fish spoilage which produce amines, biogenic amines such as putrescine

Such a molecule would be able to bind to compounds produced by rotting meat with such evocative names as cadaverine and putrescine
, and increase its electrical resistance as a result.
The final enzyme preparation showed a specific activity of 42 Umg-1 determined by the guaiacol spectrophotometric method with putrescine
as a substrate .
Polyamines like spermine, spermidine and putrescine
were detected in elevated concentrations in urine in cases of a rapid regeneration of cells of certain tissue.
The serum-free media contained 7.5 mM glucose, 5 [micro]g/mL insulin, 16.1 [micro]g/mL putrescine
, 10% bovine serum albumin, 3.7mg/mL NaHC[O.sub.3], 5.2 mg/L [Na.sub.2]Se[O.sub.3], and 3.6 mg/mL HEPES in minimum essential medium as described [21, 23, 24].
