Discovery of novel pathways of microbial arginine biosynthesis
The amino acid L-arginine is an essential component of all living organisms. Its importance resides in the variety of functions that arginine itself, along with some intermediary metabolites involved in its de novo synthesis in the cell. In many prokaryotes, fungi, and plants the de novo …

Comprehensive metabolite analysis in Chlamydomonas reinhardtii : method development and application to the study of environmental and genetic perturbations
… down-regulation. For most of the steps in arginine biosynthesis in Chlamydomonas mutants have been isolated that are deficient in the respective enzyme activities. Three strains deficient in the activities of N-acetylglutamate-5-phosphate reductase (arg1), N2 …

L-arginine overproduction in Corynebacterium glutamicum ATCC 13032
… and L-threonine. With the exception of Larginine, the biosynthesis and regulation of most of these compounds in this bacterium are relatively well characterised in the literature. The research presented here focuses on improving our understanding of the regulation of L-arginine …

Characterisation of genetic and epigenetic aberrations in paediatric high grade glioma
… signaling (DAB1), RTK signaling (PTPRE), and arginine biosynthesis (ASS1 and ASL) were frequently deregulated by methylation in these tumours. The anti-growth and anti-migratory properties of DAB1 and PTPRE were demonstrated in vitro. Preliminary investigations validated the therapeutic …

Genetic studies of mutants of Neurospora crassa lacking ornithine transcarbamylase
Arginine has long been of interest to chemists, biochemists and biologists because of its close relation-ship to urea. Srb and Horowitz (1944) isolated many arginineless mutants of Neurospora crassa and found the mutants confirmed Krebs' claim (1932) that ornithine and citrulline are precursors in …

Systems-Level Analysis of Rootstock–Scion Interactions in Apple Reveals Mechanisms of Cold Tolerance Under Field Frost Events
… B.9, including increased ascorbate metabolism, arginine biosynthesis, and protective sugars like trehalose and melibiose. Lipid remodeling and signaling metabolites, such as colnelenic acid and LysoPA, were also enriched, pointing to dynamic membrane adaptation. Interestingly, despite exhibiting …

Regulation of The Candida Albicans Arginine Biosynthetic Pathway
… are not observed, with the only exception of arginine biosynthesis. The strong upregulation of the arginine biosynthetic (<em>ARG</em>) genes suggests their importancefor <em>C. albicans </em>virulence.</p> <p>Using single cell reporters I have shown that the (<em>ARG</em>) genes are induced …

Molecular-genetic characterisation of arginine auxotrophy in the opportunistic human pathogen, Pseudomonas aeruginosa
… the emergence of amino acid auxotrophs. Arginine auxotrophs arise at high frequency in CF, and arginine is known to play an essential physiological role in Pa, so I chose to investigate the possible molecular basis of this further. I found that a transposon (Tn) mutant containing a …
