New Insight into the Relation between Adiponectin and Diabetes

Diabetes mellitus is a group of metabolic diseases. Insulin resistance is defined as a state that needs more insulin to get the biological effects achieved by a lower amount of insulin in the normal state. Several molecules which are secreted through adipocytes have been involved in insulin resistance and type 2 diabetes mellitus. Adiponectin as a 244 amino acid protein is exclusively expressed...

Proteomics gives insight into the regulatory function of chloroplast thioredoxins.

Thioredoxins are small multifunctional redox active proteins widely if not universally distributed among living organisms. In chloroplasts, two types of thioredoxins (f and m) coexist and play central roles in regulating enzyme activity. Reduction of thioredoxins in chloroplasts is catalyzed by an iron-sulfur disulfide enzyme, ferredoxin-thioredoxin reductase, that receives photosynthetic elect...

Molecular modelling of the GIR1 branching ribozyme gives new insight into evolution of structurally related ribozymes

Twin-ribozyme introns contain a branching ribozyme (GIR1) followed by a homing endonuclease (HE) encoding sequence embedded in a peripheral domain of a group I splicing ribozyme (GIR2). GIR1 catalyses the formation of a lariat with 3 nt in the loop, which caps the HE mRNA. GIR1 is structurally related to group I ribozymes raising the question about how two closely related ribozymes can carry ou...

Structural insight into African horsesickness virus infection.

African horsesickness (AHS) is a devastating disease of horses. The disease is caused by the double-stranded RNA-containing African horsesickness virus (AHSV). Using electron cryomicroscopy and three-dimensional image reconstruction, we determined the architecture of an AHSV serotype 4 (AHSV-4) reference strain. The structure revealed triple-layered AHS virions enclosing the segmented genome an...
