Picornavirus replication is critically dependent on the correct processing of a polyprotein precursor by 3C protease(s) (3C pro) at multiple specific sites with related but non-identical sequences. To investigate the structural basis of its cleavage specificity, we performed…

Choline is a quaternary amino cationic organic alcohol that is oxidized to betaine in liver and kidney mitochondria. Betaine acts as an intracellular organic osmolyte in the medulla of the kidney. Evidence is provided that kidney mitochondria have a choline transporter in…

Foot-and-mouth disease virus causes a major global agricultural problem that is difficult to control with existing vaccines. Structural analyses of the viral 3C protease not only have provided fresh insights into the catalytic mechanism of an unusual class of chymotrypsin…

During the acute phase response, cytokines induce marked alterations in lipid metabolism including an increase in serum triglyceride levels and a decrease in hepatic fatty acid oxidation, in bile acid synthesis, and in high-density lipoprotein levels. Here we demonstrate…

The ErbB3-binding protein 1 (Ebp1) is an important regulator of transcription, affecting eukaryotic cell growth, proliferation, differentiation and survival. Ebp1 can also affect translation and cooperates with the polypyrimidine tract-binding protein (PTB) to stimulate the…

The 3C protease (3C pro) from foot-and-mouth disease virus (FMDV), the causative agent of a widespread and economically devastating disease of domestic livestock, is a potential target for antiviral drug design. We have determined the structure of a new crystal form of FMDV…

During the third trimester of pregnancy, there is an increase in serum triglyceride and cholesterol levels. The mechanisms accounting for these changes in lipid metabolism during pregnancy are unknown. We hypothesized that, during pregnancy, the expression of nuclear hormone…

BACKGROUND: A commensal microbiota regulates and is in turn regulated by viruses during host infection which can influence virus infectivity. In this study, analysis of colon microbiota population changes following a low pathogenicity avian influenza virus (AIV) of the H9N2…

The limited knowledge on the role of many of the approximately 170 proteins encoded by African swine fever virus restricts progress toward vaccine development. Previously, the DP148R gene was deleted from the genome of genotype I virulent Benin 97/1 isolate. This virus…
