Arginase Explains Angina In Diabetics
In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital show that an enzyme called arginase might have a key part to play...
Blend Of Proteins Supplies Amino Acids To Muscles And Extends Growth And Repair
A new study published in The Journal of Nutrition demonstrates the benefits of consuming a protein blend for muscle protein synthesis after exercise. This study is a first-of-its-kind, conducted by re...
Epistasis as the primary factor in molecular evolution
The main forces directing long-term molecular evolution remain obscure. A sizable fraction of amino-acid substitutions seem to be fixed by positive selection, but it is unclear to what degree long-ter...
T cell activation triggers proliferation and effector-cell differentiation. Cantrell and colleagues show that TCR signaling induces upregulation of amino-acid transporters necessary for metabolic repr...
Targeted Medical announces preliminary data of amino acid-based oral formulation
Specialty pharmaceutical company Targeted Medical Pharma in Los Angeles, US, has reported preliminary data from an open-label pilot study of its amino acid-based oral formulation.
Crystal structure of the entire respiratory complex I
The atomic-resolution structure of the entire respiratory complex I is reported, with the resolution high enough to map out the locations and orientations of nearly all amino-acid side chains—some o...
Regulation of mTORC1 by the Rag GTPases is necessary for neonatal autophagy and survival
The mechanistic target of rapamycin complex 1 (mTORC1) pathway regulates organismal growth in response to many environmental cues, including nutrients and growth factors. Cell-based studies showed tha...
Arginase might play a role in development of cardiovascular disease in type II diabetics
In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital in Sweden show that an enzyme called arginase might have a key pa...

Binding of α,α-Disubstituted Amino Acids to Arginase Suggests New Avenues for Inhibitor Design.
Arginase is a binuclear manganese metalloenzyme that hydrolyzes l-arginine to form l-ornithine and urea, and aberrant arginase activity is implicated in various diseases such as erectile dysfunction,...
Macrophages, upon phagocytosing endospores of Bacillus anthracis, up-regulate the expression of the immunological isoform of nitric oxide synthase, NOS 2, concomitant with production of nitric oxide (...
Antiretroviral therapy abrogates association between arginase activity and HIV disease severity.
Arginase-induced L-arginine deprivation is emerging as a key mechanism for the downregulation of immune responses. We hypothesised that arginase activity increases with disease severity in HIV-seropos...
In eukaryotic cells amino acid deprivation triggers a response aimed to ensure cell survival in stress conditions. In the present work we analyzed the effects of amino acid deprivation on intracellula...
Recent efforts to identify treatments for myocardial ischemia reperfusion injury have resulted in the discovery of a novel series of highly potent α,α-disubstituted amino acid-based arginase inhibit...
