Nucleoprotein-based nanoscale assembly.
A system for addressing in the construction of macromolecular assemblies can be based on the biospecificity of DNA (cytosine-5) methyltransferases and the capacity of these enzymes to form abortive covalent complexes at targeted 5-fluorocytosine residues in DNA. Using this system, macromolecular assemblies have been created using two representative methyltransferases: M-HhaI and M x MspI. When ...
متن کاملThe role and importance of DNA methylation in spermatogenesis process
Background: DNA methylation is one of the epigenetic marks that are created by de novo DNA methylation and be maintained through cell division. This process is catalyzed by DNA methyltransferases. DNA methylation establishment in germ line is important, since they have the potential to regulate gene expression in offspring and improper DNA methylation patterns in germ lines has serious conseque...
متن کاملConstruction of an Eukaryotic Expression Vector Encoding Herpes Simplex Virus Type 2 Glycoprotein D and In Vitro Expression of the Desired Protein
To construct of an eukaryotic expression vector encoding herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2), an Iranian isolate of HSV-2 was propagated in HeLa cell line and its DNA was extracted and used as template in polymerase chain reactions (PCR), to amplify gD2 gene. Primers were designed and the restriction enzyme sites for EcoRI and XhoI were considered at their 5′ ends respectiv...
متن کاملStatistical Inference of In Vivo Properties of Human DNA Methyltransferases from Double-Stranded Methylation Patterns
DNA methyltransferases establish methylation patterns in cells and transmit these patterns over cell generations, thereby influencing each cell's epigenetic states. Three primary DNA methyltransferases have been identified in mammals: DNMT1, DNMT3A and DNMT3B. Extensive in vitro studies have investigated key properties of these enzymes, namely their substrate specificity and processivity. Here ...
