Structure and Activity of the Paramecium Bursaria Chlorella Virus Arginine Decarboxylase

open access: yes, 2007
The substrate specificity of enzymes has been studied with keen interest for many years. An understanding of the structural basis of specificity may help to explain how enzymes have evolved such enormous rates of catalysis above uncatalyzed reactions. By

Cytotoxicity of tumor antigen specific human T cells is unimpaired by arginine depletion. [PDF]

open access: yes, 2013
Tumor-growth is often associated with the expansion of myeloid derived suppressor cells that lead to local or systemic arginine depletion via the enzyme arginase.

Arginine methylation in subunits of mammalian pre-mRNA cleavage factor I [PDF]

open access: yes, 2010
Mammalian cleavage factor I (CF Im) is composed of two polypeptides of 25 kDa and either a 59 or 68 kDa subunit (CF Im25, CF Im59, CF Im68). It is part of the cleavage and polyadenylation complex responsible for processing the 39 ends of messenger RNA ...

The influence of L-arginine on the self-medication behaviour of Drosophila Melanogaster larvae

open access: yes, 2013
The theory of self-medication works on the premise that sick animals will change their diet to incorporate food substances that are not part of their usual diet, that will cure or alleviate the disease.

Discovery of Post‐Translationally Modified Epitopes in Autoimmunity: Someone Has to Fish so Everyone Can Eat

open access: yesImmunological Reviews, Volume 343, Issue 1, October 2026.
ABSTRACT Post‐translational modifications (PTMs) chemically diversify the ~20,000 genomically encoded proteins into millions of functional variants, and this diversity has profound consequences for T cell‐mediated immune responses. PTM‐reactive T cells have been identified across numerous autoimmune diseases and, in several cases, implicated directly ...

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

open access: yes, 1987
A homogeneous prepn. of putrescine synthase, the versatile multifunctional enzyme involved in agmatine  putrescine conversion in Cucumis sativus, also catalyzed the decarboxylation of arginine.

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7558-7574, October 2026.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.
