The structure of regenerated A. pernyi silk fibroin films was the coexistence of α helix and random coil. 指出再生柞蚕丝素膜内丝素蛋白的分子构象为α螺旋和无规线团结构共存。
During long interaction period or at high concentration of CTAB, CTAB unfolded the protein by decreasing the α-helix structure and increasing the random coil. 而住高浓度CTAB或较长作用时间时,蛋白质的二级结构被破坏,蛋白质内部氧键减弱,部分的α-螺旋结构转变为无规卷曲结构。
Circular dichroism ( CD) spectrum analysis showed that the percentage of α-helix,β-sheet and random coil of day lily tubulin is 27.24%, 24.48% and 48.28%, respectively, indicating a typical feature of globulin. 此时的最大发射峰为338nm,圆二色光谱分析二级结构表明α-螺旋占27.24%,β-折叠占24.48%,无规卷曲为48.28%,呈典型球蛋白特征。
The Results showed that the fusion region of BCR-ABL fusion protein ( p210~ ( BCR-ABL)) probably lo-cated in a B cell epitope which contained α-helix and random coil structure. 结果表明:BCR-ABL蛋白融合区位于B细胞表位内,该表位含有α-螺旋和无规则卷曲结构。
It was found that with the increase of PGG concentration, the interaction of PGG with HSA has mainly caused the change from the α-helix structure to β-turn and random coil structure. 随着药物浓度的增加,PGG和HSA之间的相互作用主要使HSA的二级结构发生了由α螺旋向β转角和无规结构的转化。
Circular dichroism studies on the recombinant SD indicated that the secondary structure of the recombinant protein had about 29.2% α-Helix, 9.3% β-Sheet, 32.7% β-Turn, 28.8% Random coil. 应用圆二色仪初步测定了重组蛋白的二级结构,重组SD的二级结构中大约有29.2%的α螺旋,9.3%β折叠,32.7%β转角,28.8%无规卷曲。
The results show that different electric field strength ranging from 1.0 to 6.0 kV · cm-1 has a different effect on the relative contents of α-helix,β-sheet,β-turn and random coil of the HRP. 结果表明:在1.0~6.0kV.cm-1范围,不同强度的电场对辣根过氧化物酶的α-螺旋、β-折叠、β-转角及无规卷曲相对含量的影响程度不同。
Spatial structure simulation indicated that periphery of this protein was α-helix, and inside were P-pleated sheet structure and random coil, perhaps it was the active centre of the combination of this protein and its substrate. 空间结构模拟表明,该蛋白的内部主要是β-折叠和一些无规卷曲,可能是酶与底物结合的活性中心,外围主要是α-螺旋。
The simulation result shows that the heating rate of the segmented helix coil heater is faster than that of the integrated heater. 模拟结果显示分段布置的螺旋盘管换热器比单层布置的螺旋管加热速度更快。
Double helix coil heat exchanger can be a good fit for smear-style cloth in water, while the bearing capacity and good heat transfer performance. 双螺旋盘管换热器能够很好的适应涂抹式布水,同时具有较好的承压能力和换热性能。
