One major difference between the human and the chicken prepro alpha 2(I) chain was that the human chain contained 21 fewer proline residues, an observation that probably explains why the triple helix of human type I procollagen unfolds at temperatures that are 1-2 degrees C lower. In ...
DNA triple-helix formation on nucleosome core particles. Effects of length of the oligopurine tractBrownP.M.FoxK.R.ingentaconnectEuropean Journal of BiochemistryBrown,P.M. and Fox,K.R. (1999) DNA triple-helix formation on nucleosome core particles - effect of length of the oligopurine tract....
aThe helix axis of DNA in vivo is usually curved, rather than linear. This is a necessary condition, as the stretched length of the human genome is about 1 meter and this length needs to be "packaged" in order to fit in the nucleus of a cell. In eukaryotes, nature solved this ...
The sequence-defined DNA oligomer bC88-DNAa consists of eight units of a branched alkyl chain-based monomer containing eight carbons, bC8, appended to a 19mer arbitrary sequence of DNA (Fig. 1A). Initially—at room temperature in aqueous solution (pH 8) with 6.25 mM Mg2+—no self-as...
Activities of ATP binding cassette (ABC) proteins are regulated by multiple mechanisms, including protein interactions, phosphorylation, proteolytic processing, and/or oligomerization of the ABC protein itself. Here we present the structure of yeast cadm

The DNA molecule is a double helix: that is two long thin strands twisted around each other like a spiral staircase. A gene is a length of DNA that codes for a specific protein.,站酷海洛,一站式正版视觉内容平台,站酷旗下品牌.授权内容包含正版商业图片、艺
Both RNA and DNA have a double helix structure. (a) True (b) False. A cell with 46 chromosomes has 46 DNA molecules. True False The building blocks of DNA are called nucleotides. True False Histone deacetylase enzymes cause chromatin to loosen to allow exposure of RNA po...
The α-helix and β-sheet are common components of the structures of proteins, and such secondary structures are defined by two dihedral angles, ψ and ϕ. Again, it is expected that 17O NMR tensors are related to the changes in the angles. To investigate dihedral angle dependence, a th...
The pGC-A monomer contains a peptide binding extracellular domain (ECD), a single helix transmembrane domain and an intracellular domain (ICD), which contains one protein kinase-like domain (PKLD) and a guanylyl cyclase catalytic domain (GCD)20. The current structural knowledge of pGC-A was ...
