Arginine decarboxylase is a component activity of the multifunctional enzyme putrescine synthase in cucumber seedlings [PDF]

, 1978
A homogenous PreParation of Putrescine synthase, the versatile multifunctional enzyme involved in agmatine →Putrescine conversion inCucumis sativus was found to catalyze enzymatic decarboxylation of arginine also.

Polyamine Induction in Postharvest Banana Fruits in Response to NO Donor SNP Occurs via l-Arginine Mediated Pathway and Not via Competitive Diversion of S-Adenosyl-l-Methionine

Antioxidants, 2019
Nitric oxide (NO) is known to antagonize ethylene by various mechanisms; one of such mechanisms is reducing ethylene levels by competitive action on S-adenosyl-L-methionine (SAM)—a common precursor for both ethylene and polyamines (PAs ...

Inhibition of putrescine biosynthesis enhanced salt stress sensitivity and decreased spermidine content in rice seedlings

Biologia Plantarum, 2017
The effect of polyamine biosynthesis inhibitors on the salt stress response of rice seedlings was investigated. For this, DL-α-difluoromethylarginine (DFMA) and DL-α-difluoromethylornithine (DFMO), two competitive inhibitors of arginine decarboxylase ...

Putrescine Biosynthesis Inhibition in Tomato by DFMA and DFMO Treatment

Bio-Protocol, 2016
This protocol can be used to inhibit the biosynthesis of polyamines, specifically putrescine, in tomato plants grown with NH4+ as a solely N source. In general, polyamines are positively charged small metabolites implicated in physiological processes ...

Arginine-dependent mRNA destabilization.

, 2019
(A) A partial diagram of polyamine biosynthesis. Putrescine can be produced from ornithine via speC and speF encoding a constitutive and inducible ornithine decarboxylase, respectively or from arginine in two steps via speA and speB encoding arginine ...

The effects of acute arginine supplementation on 10 mile cycling time trial performance in young adult males [PDF]

, 2012
L-arginine is one of the most metabolically versatile amino acids in the human body, most notably serving as the pre-cursor for the biosynthesis of nitric oxide (NO).

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
