Corynebacterineae is a specific suborder of Gram-positive bacteria that includes Mycobacterium tuberculosis and Corynebacterium glutamicum. The cell wall of these bacteria is composed of a heteropolymer of peptidoglycan (PG) linked to arabinogalactan (AG), which in turn is covalently associated with an atypical outer membrane, here called mycomembrane (M). The latter structure has been visualiz...
Abstract An exopolysaccharide (EPS) was isolated from Lactobacillus plantarum Ts and purified by size exclusion chromatography train. L. showed the highest production (9.4 ± 0.8 g/l) of EPS. Furthermore, cultured in medium with volume 5 L EPS extracted ethanol precipitation. By HPLS analysis demonstrated, that has two fractions - polymer olygomer. The molecular mass both is respectively 8.3x104...
We present a general thermodynamic picture of the folding of RNA-like heteropolymer based on the basic physical principles. The Hamiltonian of the model includes all characteristic interactions explicitly. A particular attention is paid to the electrostatic interactions whose role in the RNA folding is known to be crucial. In this paper we study RNA folding with the full Hamiltonian and describ...
A constant ratio of ferritin heavy chain homolog (HCH) and light chain homolog (LCH) subunits seems to be required to compose the ferritin heteropolymer protein in insects. However, the mechanism by which insect LCH genes regulate protein levels remains unclear. We report that alternative promoters and alternative splicing contribute to maintaining a constant ratio of the two subunits, BdFer1HC...
Corona phase molecular recognition (CoPhMoRe) uses a heteropolymer adsorbed onto and templated by a nanoparticle surface to recognize a specific target analyte. This method has not yet been extended to macromolecular analytes, including proteins. Herein we develop a variant of a CoPhMoRe screening procedure of single-walled carbon nanotubes (SWCNT) and use it against a panel of human blood prot...
The kinetic behavior of a three-dimensional oo-lattice heteropolymer model is studied in terms of the time dependence of the average mean-square displacement between conngura-tions. It is found that at short timescales similar behavior is obtained even for sequences with very diierent thermodynamic properties. Furthermore, the degree of cooperativity in the folding process is examined by studyi...
