Foot-and –Mouth disease virus (FMDV) is a positive sense RNA virus and the genome codes for single polyprotein. The FMDV L protein is located at the N terminus of the polyprotein and is the first gene product released from the nascent polyprotein. The leader L protease which is involved in pathogenesis has two known functions: (i) auto-catalytic removal from the N terminus of the viral polyprotein and (ii) cleavage of the p220 subunit of the eukaryotic initiation factor 4F complex, which helps to shut off host protein synthesis. To explore the role of L protease in FMDV pathogenesis we generat

The highly conserved ATP-dependent Lon protease plays important roles in diverse biological processes. The lon gene is usually nonessential for viability; however, lon mutants of several bacterial species, although viable, exhibit cellular defects. Here, we show that a lack of Lon protease causes pleiotropic effects in the rice pathogen Burkholderia glumae. The null mutation of lon produced three colony types, big (BLONB), normal (BLONN), and small (BLONS), in Luria–Bertani (LB) medium. Colonies of the BLONB and BLONN types were re-segregated upon subculture, while those of the BLONS type were

Abstract The Papain-like protease (Plpro) of the SARS-CoV-2 virus represents a potential therapeutic target for combating Coronavirus Disease 2019 (COVID-19). Due to its practicality and cost-effectiveness, recombinant production of Plpro is conventionally achieved through Escherichia coli. However, this process’s synthetic Luria-Bertani (LB) medium remains economically burdensome. This study explores the feasibility of substituting LB medium with whey, a by-product of cheese processing renowned for its rich nutritional profile.

Foot-and-mouth disease (FMD) is a highly contagious disease caused by FMD virus (FMDV) in cloven-hoofed animals. Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) are representative receptors in the cytoplasm for the detection of viral RNA and trigger antiviral responses, leading to the production of type I interferon. Although MDA5 is a crucial receptor for sensing picornavirus RNA, the interplay between MDA5 and FMDV is relatively unknown compared to the interplay between RIG-I and FMDV. Here, we observed that the FMDV infection inhibits MDA5 protei

ABSTRACT Vibrio cholerae strains of the O1 serogroup that typically cause epidemic cholera can be classified into two biotypes, classical and El Tor. The El Tor biotype emerged in 1961 and subsequently displaced the classical biotype as a cause of cholera throughout the world. In this study we demonstrate that when strains of the El Tor and classical biotypes were cocultured in standard LB medium, the El Tor strains clearly had a competitive growth advantage over the classical biotype starting from the late stationary phase and could eventually take over the population. The classical biotype p

Summaryvon Willebrand factor (vWF) is a complex multimeric plasma glycoprotein, that plays a critical role in the mediation of platelet adhesion to the damaged vascular wall, and functions as a carrier protein for factor VIII. vWF has a domain structure consisting of repeated A, B, C, and D domains. The A1 domain is involved in binding to the platelet receptor glycoprotein (GP) lb, and the A3 domain has a binding site for collagen. A function of the A2 domain has not been described, although point mutations identified in von Willebrand disease (vWD) type 2A patients are localized in this domai

Fermentations were performed aerobically or anaerobically at 37 °C using crude or pre-heated whey (10 min at 65, 75 or 85 °C). Under aerobic conditions, growth of lactobacilli was poor and protein hydrolysis did not occur.

Mucoid strains of Pseudomonas aeruginosa that overproduce the exopolysaccharide alginate are a frequent cause of chronic respiratory infections in cystic fibrosis (CF) patients. The overproduction of alginate by these strains is often caused by mutations within mucA of the algU mucABCD gene cluster. This gene cluster encodes an extreme stress response system composed of the ECF alternative sigma factor AlgU, the anti-sigma factor MucA located in the inner membrane and the negative regulator MucB located in the periplasm. Most of the mutations in mucA found in mucoid strains cause a truncation
