Amino AcidsProteins氨基酸类蛋白质类Using a semiempirical quantum mechanical procedure (FCPAC) we have calculated the partial atomic charges of amino acids from 494 high-resolution protein structures. To analyze the influence of the protein's environment, we considered each residue under two conditions...
A large data base of 6-31G*, MNDO, AM1, and PM3 electrostatic potential (ESP) derived point charges of amino acids and monosaccharides is analyzed. We find that MNDO correlates well with 6-31G* ESP derived point charges, while AM1 and PM3 do so quite poorly. Furthermore, scaling ...
The permeabilities of amino acids through bilayer lipid membranes were determined using small unilamellar vesicles (SUV). Alanine, lysine, arginine, and glutamate show permeabilities on the order of 10-10-10-11cm/s in the case of SUV prepared from dimyristoylphosphatidylcholine and dicetylphosphate....
Studies involving AQP0-transfected L-cells, and lipid vesicles indicated that CTCA was due to the electrostatic interaction between the positively charged amino acids of AQP0 extracellular loops and the negative charges of the plasma membrane. Schematic models are provided to illustrate the mechanism....
S2d). Quantification of scFv stability relied on the energy given in Joules per amino acid, a normalization against protein size. As shown in Supplementary information, Fig. S2e, no significant correlations between CAR tonic signaling indexes and scFv stabilities were observed (P > 0.1, ...
α-Synuclein (140 amino acids), one of the causative proteins of Parkinson's disease, forms amyloid fibrils in brain neuronal cells. In order to further explore the contributions of the C-terminal region of α-synuclein in fibril formation and also to understand the overall mechanism of fibril...
The occurrence of hydrophobic amino acids, which could be responsible to induces clustering in a 从质谱,它可以结束这peptidepresents低分子量。 这信息,与他一起从红外波谱得到的数据,建议与抗菌lipopeptides的一个关系。 发生疏水氨基酸,可能是负责任的导致成群在含水媒介,同早先被描绘的抗菌肽联系在一起从B。
Strong fei peptide A1-17 (Dyn A1-17) is separates the depuration from the pig pituitary gland and the intestinal tract one kind in meconium peptide which is composed by 17 amino acids, the molecular weight is 2147.5.[translate] ascalpore 忙乱[translate] ...
Subsequently, the electrode with n-SNF/ITO was subjected to an electrochemical-assisted self-assembly (EASA) method in a precursor solution containing amino-functionalized siloxane. This process led to the growth of positively charged p-SNF with abundant amino groups. EASA is a rapid method for ...
A comprehensive characterization of heterogeneous anion exchange MA-40 and MA-41 membranes, differing in the nature of functional groups and the ion-exchange capacity (3.32 and 1.41 mmol/gdry, respectively), was carried out. The MA-40 membrane contains low basic secondary and tertiary amino groups...
