Polyamines directly promote antizyme-mediated degradation of ornithine decarboxylase by the proteasome [PDF]
Ornithine decarboxylase (ODC), a ubiquitin-independent substrate of the proteasome, is a homodimeric protein with a rate-limiting function in polyamine biosynthesis.

Characterization of the Link between Ornithine, Arginine, Polyamine and Siderophore Metabolism in Aspergillus fumigatus. [PDF]
The opportunistic fungal pathogen Aspergillus fumigatus produces siderophores for uptake and storage of iron, which is essential for its virulence. The main precursor of siderophore biosynthesis (SB), ornithine, can be produced from glutamate in the ...

Untargeted metabolomics reveals a lack of synergy between nifurtimox and eflornithine against trypanosoma brucei [PDF]
A non-targeted metabolomics-based approach is presented that enables the study of pathways in response to drug action with the aim of defining the mode of action of trypanocides.

Sensing and adaptation to low pH mediated by inducible amino acid decarboxylases in Salmonella. [PDF]
During the course of infection, Salmonella enterica serovar Typhimurium must successively survive the harsh acid stress of the stomach and multiply into a mild acidic compartment within macrophages.

Leishmania donovani: cellular control of ornithine decarboxylase in promastigotes [PDF]
Ornithine decarboxylase, a key enzyme in polyamine biosynthesis, is essential for normal cell growth and proliferation. Furthermore, the inhibition of this enzyme is a potential way of controlling such growth.

mRNA dynamics and alternative conformations adopted under low and high arginine concentrations control polyamine biosynthesis in Salmonella. [PDF]
Putrescine belongs to the large group of polyamines, an essential class of metabolites that exists throughout all kingdoms of life. The Salmonella speF gene encodes an inducible ornithine decarboxylase that produces putrescine from ornithine.

A molecular mechanism for eflornithine resistance in African trypanosomes [PDF]
Human African trypanosomiasis, endemic to sub-Saharan Africa, is invariably fatal if untreated. Its causative agent is the protozoan parasite Trypanosoma brucei.
