蛋白质二级结构(secondary structure) 二级结构是指多肽链借助于氢键沿一维方向排列成具有周期性的结构的构象,是多肽链局部的空间结构(构象),主要有α-螺旋、β-折叠、β-转角等几种形式,它们是构成蛋白质高级结构的基本要素. α-螺旋(α-helix)是蛋白质中最常见最典型含量最丰富的二级结构元件.在α螺旋中,每 个...
β-turn structureC-terminal octapeptide1II n.m.r. studiesoxyntomodulinsalt bridgeThe octapeptide Lys-Arg-Asn-Lys-Asn-Asn-Ile-Ala (Arg4 in the human sequence) is the C-terminal part of porcine oxyntomodulin, an endogeneous peptide which is a potent inhibitor of stimulated acid secretion. This ...
This suggests that incorporation of the azaXaa residue into the i + 2 position of designed peptides could stabilize the -turn structure. The model azaLeu-containing peptide, Boc-Phe-azaLeu-Ala-OMe, which is predicted to adopt a -turn conformation was designed and synthesized in order to ...
The redox-dependent changes in secondary structure of cytochromes c from horse, cow, and dog hearts in water at 20 degrees C have been determined by amide I infrared spectroscopy. Second derivative amide I spectra were obtained by use of a procedure that includes a convenient method for the ef...

The third peptide, B-10284, a des-Arg9 analog with a C-terminal amide and a very potent B2 antagonist, had no definite solution structure. The high activity of these pep- tides emphasizes the importance of the N-terminal β-turn and the hydrophobic character at the C-terminus in ...
Whereas the solution conformation of ±-MSH-ND revealed a stable type I -turn structure, [Gln6]±-MSH-ND(610) revealed a tight -turn composed of Gln6 d -Phe7Arg8. Replacement of the His6 residue of ±-MSH-ND by Gln, Asn, Arg or Lys decreased not only the receptor binding, but ...
The C-CONH(CH3) fragment exhibits significant conformational flexibility; however, a low-energy conformer resembles closely the beta II-turn folded conformations of the x-ray structure of the related model peptide trans-BuCO-L-Pro-Me-D-Ala-NHMe. On the contrary, the cis isomer adopts open ...
The structure of the human erythrocyte facilitative glucose transporter (GLUT1) has been intensively investigated using a wide array of chemical and biophysical approaches. Despite the lack of a crystal structure for any of the facilitat... P.W. Hruz,M.M. Mueckler - 《Molecular Membrane Biology...
