Detection of Mycoplasma Infection of Mammalian Cells

BioTechniques, 1997
Mycoplasma infection was detected in cultures of COS cells with a novel, simple assay that detects the conversion of arginine to citrulline by the enzyme, arginine deiminase, specific to all species of mycoplasma.

Synthesis and characterization of ZnS quantum dots and application for development of arginine biosensor

Sensing and Bio-Sensing Research, 2017
Arginine deiminase co-immobilized with ZnS QDs coupled micro-disk was applied for the sensing of arginine in real and spiked fruit samples. Intracellular arginine deiminase from Lactococcus lactis MTCC 460 was partially purified by ammonium sulphate ...

Mucoadhesive Buccal Films for Local Delivery of Lactobacillus brevis

Pharmaceutics, 2020
The aim of this work was to prepare mucoadhesive buccal films for local release of Lactobacillus brevis CD2, which shows interesting anti-inflammatory properties due to its high levels of arginine deiminase.

Role of arginine deiminase in growth of Mycoplasma hominis [PDF]

Journal of Bacteriology, 1976
Arginine has been considered as the major energy source of nonglycolytic arginine-utilizing mycoplasmata. When three strains of Mycoplasma arginini, and one strain each of Mycoplasma arthritidis, Mycoplasma fermentans, Mycoplasma gallinarum, Mycoplasma gallisepticum and Mycoplasma hominis were grown in the medium with high arginine concentration (34 mM)

Structural characterization of the enzymes composing the arginine deiminase pathway in Mycoplasma penetrans.

PLoS ONE, 2012
The metabolism of arginine towards ATP synthesis has been considered a major source of energy for microorganisms such as Mycoplasma penetrans in anaerobic conditions.

Intracellular expression of arginine deiminase activates the mitochondrial apoptosis pathway by inhibiting cytosolic ferritin and inducing chromatin autophagy

BMC Cancer, 2020
Background Based on its low toxicity, arginine starvation therapy has the potential to cure malignant tumors that cannot be treated surgically. The Arginine deiminase (ADI) gene has been identified to be an ideal cancer-suppressor gene.

The arginine deaminase system plays distinct roles in Borrelia burgdorferi and Borrelia hermsii.

PLoS Pathogens, 2022
Borrelia species are amino acid auxotrophs that utilize di- and tri- peptides obtained through their oligopeptide transport system to supply amino acids for replicative growth during their enzootic cycles.

Catabolic Ornithine Carbamoyltransferase Activity Facilitates Growth of Staphylococcus aureus in Defined Medium Lacking Glucose and Arginine

mBio, 2022
Previous studies have found that arginine biosynthesis in Staphylococcus aureus is repressed via carbon catabolite repression (CcpA), and proline is used as a precursor. Unexpectedly, however, robust growth of S.

Structure and Biosynthesis of Mangotoxin Produced by the Plant Pathogen Pseudomonas syringae

Angewandte Chemie, EarlyView.
The structure of mangotoxin remained elusive for over two decades. Here, mangotoxin was isolated from the native producer, Pseudomonas syringae pv. syringae, and was determined to be an alkyne‐containing dipeptide. Mangotoxin inhibited the growth of multidrug‐resistant human pathogen Klebsiella pneumoniae.

Mapping of the arginine deiminase gene in Pseudomonas aeruginosa [PDF]

Journal of Bacteriology, 1982
A mutant of Pseudomonas aeruginosa PAO lacking arginine deiminase activity (arcA) was isolated by screening for a derivative of an arcB mutant (deficient in catabolic ornithine carbamoyltransferase) that did not excrete citrulline under conditions of limited aeration. The arcA mutation was highly cotransducible with arcB.
