DNA Ligases
DNA ligases play an integral role in DNA repair and replication through catalyzing the formation of phosphodiester bonds. Two classes of DNA ligase have been identified: ATP-dependent (EC 6.5.1.1), and NAD+-dependent (EC 6.5.1.2).
We are sorry, but we currently do not have any DNA Ligase products at this time. Please feel free to send us your requirements via our New Product Suggestions form.
DNA ligases play an integral role in DNA repair and replication through catalyzing the formation of phosphodiester bonds. Two types of DNA ligase have been identified: ATP-dependent DNA ligases (EC 6.5.1.1), and NAD+-dependent DNA ligases (EC 6.5.1.2).
The ATP-dependent DNA ligases are divided into four classes: DNA ligase I, II, III and IV. DNA ligase I links Okazaki fragments to form a continuous strand of DNA; DNA ligase II is an alternatively spliced form of DNA ligase III, found only in non-dividing cells; DNA ligase III is involved in base excision repair; and DNA ligase IV is involved in the repair of DNA double-strand breaks by non-homologous end joining (NHEJ).
