Specific measurement of putrescine with putrescine oxidase and aminobutyraldehyde dehydrogenase.

Agricultural and Biological Chemistry, 1988
A simple and rapid spectrophotometric method, based upon the UV absorption of NADH, for the measurement of putrescine by the combined use of aminobutyraldehyde dehydrogenase (EC 1.2.1.19) and putrescine oxidase (EC 1.4.3.10) was established. Simplified purification procedures for the analytical use of aminobutyraldehyde dehydrogenase of Pseudomonas ...

Putrescine biosynthesis in mammalian tissues [PDF]

Biochemical Journal, 2004
l-Ornithine decarboxylase provides de novo putrescine biosynthesis in mammals. Alternative pathways to generate putrescine that involve ADC (l-arginine decarboxylase) occur in non-mammalian organisms. It has been suggested that an ADC-mediated pathway may generate putrescine via agmatine in mammalian tissues.

Foliar application of putrescine alleviates terminal drought stress by modulating water status, membrane stability, and yield- related traits in wheat (Triticum aestivum L.)

Frontiers in Plant Science, 2023
Drought stress is one of the major limitations to the growth and yield productivity of cereal crops. It severely impairs the early growing and grain -filling stages of wheat.

PstSCAB and SapBCDF are putrescine exporters in Proteus mirabilis

Microbiology Spectrum
Proteus mirabilis is a cause of urinary tract infection. Putrescine, an aliphatic amine, acts as a messenger molecule during P. mirabilis urothelial invasion. Inhibition of putrescine-mediated cell-cell communication in P.
