Comparative evaluation of stable TAFIa variants: importance of alpha-helix 9 and beta-sheet 11 for TAFIa (in)stability. J Thromb Haemost. 2007;5:2105-2112.Ceresa E, De Maeyer M, Jonckheer A, Peeters M, Engelborghs Y, Declerck PJ, Gils A. Comparative evaluation of stable TAFIa ...
This section provides a quick introduction of protein secondary structures, alpha helix and beta sheet. Both structures are stabilized by hydrogen bonds between oxygen atoms and hydrogen atoms of two amino acid residues lined up side by side.©...
The FTIR spectra and 1H and 13C solid-state NMR results indicate that the peptides, arranged mostly in a beta-sheet structure in feather, reorganize into a mainly alpha-helix and less beta-sheet mixed secondary structure, when self-assemble from the solution at room temperature. MALDI-ToF-...
Alpha Helix and Beta Sheet The primary structure of a protein is the amino acid sequence of the polypeptide chain. The way the polypeptide chain forms hydrogen bonds determines the secondary structure. There are two main types of secondary structures in proteins, alpha helices and beta pleated ...
Beta Pleated Sheet:The structure of feathers is similar to the structure of beta pleated sheet. Features of the structure: Alpha Helix:In alpha helix structure, there are 3.6 amino acids per turn of the helix. All thepeptide bondsare trans and planar, and the N-H groups in the peptide bo...
The meaning of ALPHA-HELIX is the coiled structural arrangement of many proteins consisting of a single chain of amino acids stabilized by hydrogen bonds.
alpha-helix structure : The peptide chains coiled up to form right handed helix involving H-bonding (Intramolecular). beta-pleated sheets : The peptide chains lie side by side together by intermolecular hydrogen bonding.
The meaning of ALPHA-HELIX is the coiled structural arrangement of many proteins consisting of a single chain of amino acids stabilized by hydrogen bonds.
HIF-1 is a heterodimer consisting of an alpha and beta subunit, both belonging to the basic-helix-loop-helix Per-aryl hydrocarbon receptor nuclear translocator-Sim (PAS) family of transcription factors. HIF1 functions as a transcriptional regulator of the adaptive response to hypoxia....
Polypeptides prepared from the racemic Boc-D,L-Lys NCA are unlikely to have secondary structures like α-helix and β-sheet. Kinetics analysis We studied the kinetics of LiHMDS-initiated polymerization for BLG NCA, Boc-D,L-Lys NCA and Boc-L-Lys NCA. The rate of polymerization, kp[I], ...
