多年来的研究表明,脑电图(electroencephalography,EEG)信号的时间变化在许多时间范围内均表现出长期相关性,表明存在自不变和自相似结构(self-invariant and self-similar structures)。这种结构可以使用非线性分析和压缩方法来捕获,比如Lempel-Ziv复杂度…
蛋白质生物学:从序列到结构和疾病 Select the active site residues E35 and D52 of 1LZC. Label, colour (purple) and show only the two residues as sticks (submit the image). Which of the two residues interact with the ligand? Describe the potential …
蛋白质生物学:从序列到结构和疾病 Generate an image of 1LZC with cartoon form coloured in an N-terminal to C-terminal rainbow (elem C). Show the ligand in ball and sticks view coloured with a purple backbone and coloured by element. Label all the…
蛋白质生物学:从序列到结构和疾病 Show all the residues within 3.5 of the ligand in 1LZC? Label these residues and identify the specific atoms that form H-bonds with the ligand (submit an image). Identify any hydrophobic interactions and explain…
蛋白质生物学:从序列到结构和疾病 Create a selection of the residues L25-E35, and S50-G54 of 1LZC. How many residues are in the helix and how many turns of helix are there? Explain if this corresponds to the expected periodicity of an alpha helix…
