DNA microstructure influences selective binding of small molecules designed to target mixed-site DNA sequences
Specific targeting of protein–nucleic acid interactions is an area of current interest, for example, in the regulation of gene-expression. Most transcription factor proteins bind in the DNA major groove; however, we are interested in an approach using small molecules to target the minor groove to control expression by an allosteric mechanism. In an effort to broaden sequence recognition of DNA-...
متن کاملDBSI: DNA-binding site identifier
In this study, we present the DNA-Binding Site Identifier (DBSI), a new structure-based method for predicting protein interaction sites for DNA binding. DBSI was trained and validated on a data set of 263 proteins (TRAIN-263), tested on an independent set of protein-DNA complexes (TEST-206) and data sets of 29 unbound (APO-29) and 30 bound (HOLO-30) protein structures distinct from the training...
متن کاملInvestigation and Determination the Binding Site of Glycyrrhizin of Liquorice to DNA
Glycyrrhizin(GL), is a triterpenoid saponin found in glychyrrhiza glabra (liquorice). This compound is a frequently used and very effective drug for the treatment of various malignancies. This study was designed to examine the interactions of glycyrrhizin with calf thymus DNA in aqueous solution at physiological conditions. FTIR spectroscopic method was used to determine the ligand binding mode...
متن کاملArtificial site-selective DNA cutters to manipulate single-stranded DNA
Recent progress regarding the development of artificial site-selective DNA cutters by chemical approaches are reviewed herein, with a special focus on site-selective cutters for single-stranded DNA. We employ a Ce(IV)/EDTA complex to serve as the catalyst, because it efficiently and selectively cuts single-stranded DNA. Using two complementary oligonucleotide additives, a gap structure is forme...
متن کاملAntineoplastic DNA-binding compounds: intercalating and minor groove binding drugs.
DNA intercalating and minor groove binding compounds are new weapons in the battle against malignant diseases. These antineoplastic agents target the DNA molecule and interfere with the cell cycle leading to rapidly proliferating cell death. They are mainly derivates of a naturally occurring organic compound derived from a microorganism or plant. Intercalators usually act as topoisomerase I and...
