The estimation of affinity constants for the binding of model peptides to DNA by equilibrium dialysis.
The binding of lysine model peptides of the type Lys-X-Lys, Lys-X-X-Lys and Lys-X-X-X-Lys (X = different aliphatic and aromatic amino acids) has been studied by equilibrium dialysis. It was shown that the strong electrostatic binding forces generated by protonated amino groups of lysine can be distinguished from the weak forces stemming from neutral and aromatic spacer amino acids. The overall ...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولPredicting the binding affinity of MHC class II peptides.
MHC (Major Histocompatibility Complex) proteins are categorized under the heterodimeric integral membrane proteins. The MHC molecules are divided into 2 subclasses, class I and class II. Two classes differ from each other in size of their binding pockets. Predicting the affinity of these peptides is important for vaccine design. It is also vital for understanding the roles of immune system in v...
متن کاملDesigned arginine-rich RNA-binding peptides with picomolar affinity.
Arginine-rich peptide motifs (ARMs) capable of binding unique RNA structures play critical roles in transcription, translation, RNA trafficking, and RNA packaging. Bacteriophage ARMs necessary for transcription antitermination bind to distinct boxB RNA hairpin sequences with a characteristic induced alpha-helical structure. Characterization of ARMs from lambdoid phages reveals that the dissocia...
متن کاملDNA sequence correlations shape nonspecific transcription factor-DNA binding affinity.
Transcription factors (TFs) are regulatory proteins that bind DNA in promoter regions of the genome and either promote or repress gene expression. Here, we predict analytically that enhanced homooligonucleotide sequence correlations, such as poly(dA:dT) and poly(dC:dG) tracts, statistically enhance nonspecific TF-DNA binding affinity. This prediction is generic and qualitatively independent of ...
