Tianlongkechuanling Inhibits Pulmonary Fibrosis Through Down-Regulation of Arginase-Ornithine Pathway

Frontiers in Pharmacology, 2021
Background: Pulmonary Fibrosis (PF) is an interstitial lung disease characterized by excessive accumulation of extracellular matrix in the lungs, which disrupts the structure and gas exchange of the alveoli.

Retrieving sequences of enzymes experimentally characterized but erroneously annotated : the case of the putrescine carbamoyltransferase

BMC Genomics, 2004
Background Annotating genomes remains an hazardous task. Mistakes or gaps in such a complex process may occur when relevant knowledge is ignored, whether lost, forgotten or overlooked.

Identification and characterization of a Streptococcus suis immunogenic ornithine carbamoytransferase involved in bacterial adherence

Journal of Microbiology, Immunology and Infection, 2020
Background: Streptococcus suis (SS) is a major swine pathogen and a serious zoonotic pathogen causing septicemia and meningitis in piglets and humans. Using an immunoproteomic approach, we previously brought evidence that ornithine carbamoytransferase ...

Putrescine metabolism in pea seedligs

Acta Societatis Botanicorum Poloniae, 2015
The effect of putrescine (Putr.) and N-carbamoylputrescine (N-CPutr.) fed to excised pea seedlings was studied. Contrary to great toxicity of higher than 0.5% Putr., N-CPutr. even at higher concentration was not toxic for the plants.

Differential proteomic analysis of Clostridium perfringens ATCC13124; identification of dominant, surface and structure associated proteins

BMC Microbiology, 2009
Background Clostridium perfringens is a medically important clostridial pathogen causing diseases in man and animals. To invade, multiply and colonize tissues of the host, a pathogen must be able to evade host immune system, and obtain nutrients ...

Expression of the gene for resistance to phaseolotoxin (argK) depends on the activity of genes phtABC in Pseudomonas syringae pv. phaseolicola. [PDF]

PLoS ONE, 2012
The bacterium Pseudomonas syringae pv. phaseolicola produces phaseolotoxin in a temperature dependent manner, being optimally produced between 18°C and 20°C, while no detectable amounts are present above 28°C.
