Myelin basic protein (MBP), a highly cationic protein that maintains the structure of the myelin sheath, associates with tubulin in vivo. The in vitro assembly of tubulin by MBP was examined here using several assays. The unmodified C1 component of 18.5 kDa bovine MBP (bC1) assembled tubulin into microtubules in a dose-dependent manner via filamentous intermediates, and was able simultaneously ...

Half-metallicity rising from the s/p electrons has been one of the hot topics in spintronics. Based on the first-principles of calculation, we explore the magnetic properties of the B-doped graphitic heptazine carbon nitride (gh-C3N4) system. Ferromagnetism is observed in the B-doped gh-C3N4 system. Interestingly, its ground state phase (BC1@gh-C3N4) presents a strong half-metal property. Furth...

Seed coat color is an important agronomic trait in sesame, as it is associated with seed biochemical properties, antioxidant content and activity and even disease resistance of sesame. Here, using a high-density linkage map, we analyzed genetic segregation and quantitative trait loci (QTL) for sesame seed coat color in six generations (P1, P2, F1, BC1, BC2 and F2). Results showed that two major...

Myxothiazol, an antibiotic from Myxococcus fulvus, which inhibits mitochondrial respiration in the bc1 complex of the respiratory chain, has effects on the redox components of isolated succinate-cytochrome c reductase complex which suggest that it interacts with both cytochrome b and the iron-sulfur protein of the bc1 complex. The inhibitor appears to increase the midpoint potentials of cytochr...

One of the most widely used strategies to improve drug diffusion through skin is use permeation enhancers. The aim this work was investigate effect two biosurfactants (BS), produced by Lactobacillus crispatus BC1 and gasseri BC9, on profile hydrocortisone (HC, model drug). HC aqueous solubility in vitro studies porcine were performed presence BC1-BS BC9-BS at concentrations below above critical...

Small diffusible redox proteins facilitate electron transfer in respiration and photosynthesis by alternately binding to integral membrane proteins. Specific and transient complexes need to be formed between the redox partners to ensure fast turnover. In respiration, the mobile electron carrier cytochrome c shuttles electrons from the cytochrome bc1 complex to cytochrome c oxidase. Despite exte...

At deep-sea vent systems, hydrothermal emissions rich in reductive chemicals replace solar energy as fuels to support microbial carbon assimilation. Until recently, all the microbial components at vent systems have been assumed to be fostered by the primary production of chemolithoautotrophs; however, both the laboratory and on-site studies demonstrated electrical current generation at vent sys...

Management of rhizomania includes planting in cool soils, proper irrigation and soil fumigation with methyl bromide. However, breeding for resistance to BNYW is the most critical aspect of rhizomania control In this study, the inheritance of resistance to beet necrotic yellow vein virus (BNYW) in B. vulgaris subsp. maritima. wild beet (WB) accession WB42 was investigated. Crosses between resist...
