Nhei fermentas pdf WordPress.com. Dna ligase (ec 6.5.1.1) is the enzyme at the heart of the dna ligation reaction. it covalently joins the phosphate backbone of dna with blunt or compatible cohesive ends (see figure 1 ) and it’s natural role is in repairing double strand breaks in dna molecules., www.fermentas.com © 2002 fermentas canada mbi fermentas inc. 830 harrington court, burlington, on l7n 3n4 phone: 1 800 3409026 fax: 1 800 4728322 e-mail: info.

Improvement of DNA adenylation using T4 DNA ligase with a. The t4 dna ligase catalyzes the formation of a phosphodiester bond between juxtaposed 5'-phosphate and 3'-hydroxyl termini in duplex dna or rna with blunt or cohesive-end termini. the enzyme repairs single-strand nicks in duplex dna, rna or dna/rna hybrids but has no activity on single-stranded nucleic acids. the t4 dna ligase requires atp as cofactor, t4 dna ligase is a widely used enzyme in the field of molecular biology. it is commonly used in cloning to covalently join dna insert of interest into the open ends of a cloning vector. in the presence of t4 dna ligase and atp, the 3’ hydroxyl end and the 5’ phosphate end of dna fragment(s) are joined together by forming a phosphodiester bond (4). in ligation experiments, several.
