Properties of putrescine uptake by PotFGHI and PuuP and their physiological significance were studied using a polyamine biosynthesis and uptake deficient Escherichia coli KK3131 transformed with pACYC184 containing potFGHI or puuP. Putrescine uptake activity of E. coli KK3131 transformed with pACYC184-PotFGHI was higher than that of E. coli 3131 transformed with pACYC-PuuP when cells were cultured in the absence of putrescine. Putrescine uptake by PotFGHI was both ATP and membrane potential… Expand
Spot 42 RNA regulates putrescine catabolism in Escherichia coli by controlling the expression of puuE at the post-transcription level
TLDR
This work revealed the regulatory role of Spot 42 in putrescine catabolism, in the switch between favorable and non-favorable carbon source utilization, and in the balance of metabolism of carbon and nitrogen sources. Expand
Effect of Spermidine Analogues on Cell Growth of Escherichia coli Polyamine Requiring Mutant MA261
TLDR
The degree of stimulation of cell growth by spermidine analogues at the different temperatures is dependent on the stimulation of protein synthesis by some components of the polyamine modulon. Expand
Putrescine biosynthesis and export genes are essential for normal growth of avian pathogenic Escherichia coli
TLDR
In vitro growth of APEC (ST117- O83:H4) strain, but not E. coli MG1655, was affected, despite the high similarity of the genetic make-up of biosynthesis and transport genes, suggesting blocking these metabolic reactions may be a suitable way to prevent APEC growth in the host without disturbing the commensal E coli population.

Polyamine Catabolism in Prokaryotes
Polyamines play important roles in cell growth and proliferation. In particular, these biogenic compounds are involved in the regulation of transcription and translation processes required forExpand
Recent Advances in Bacterial Polyamine Transport Systems
Many bacteria take up external polyamines to optimize their growth and adaptation to the environment. Furthermore, cell-to-cell communication using polyamines recently reported requires export ofExpand
In vivo influence of in vitro up-regulated genes in the virulence of an APEC strain associated with swollen head syndrome
TLDR
This work was developed to study if over-expressed genes in a microarray assay could be potentially involved in the pathogenicity of an Avian Pathogenic Escherichia coli strain isolated from a swollen head syndrome case. Expand
Identification of Functional Amino Acid Residues Involved in Polyamine and Agmatine Transport by Human Organic Cation Transporter 2
TLDR
The results indicate that the recognition sites for putrescine, agmatine and spermidine on hOCT2 strongly overlap, consistent with the observation that the three amines are transported with similar affinity and velocity. Expand
γ-Glutamyltranspeptidase essential for the metabolism of γ-glutamyl compounds in bacteria and its application.
TLDR
Using transpeptidation activity, efficient enzymatic production of useful γ-glutamyl compounds, such as prodrug for Parkinson's disease, theanine and kokumi compound, was enabled. Expand
Utilization of Host Polyamines in Alternatively Activated Macrophages Promotes Chronic Infection by Brucella abortus
TLDR
It is demonstrated that increased intracellular availability of polyamines induced by arginase-1 expression in IL-4/IL-13-induced AAMs promotes chronic persistence of B. abortus within this niche and suggested that targeting of this pathway may aid in eradicating chronic infection. Expand
Two different routes for double-stranded DNA transfer in natural and artificial transformation of Escherichia coli.

TLDR
It is concluded that dsDNA transfers across the two membranes through different routes in natural and artificial transformation of E. coli. Expand
