Table \(\PageIndex{1}\) summarizes the enzymes involved in prokaryotic DNA replication and the functions of each. Formation of a phosphodiester bond between the 5' phosphate of the donor and the 3' hydroxyl of the acceptor. [2] A pictorial example of how a ligase works (with sticky ends) Ligase will also work with blunt ends, although higher enzyme concentrations and different reaction conditions are required. See more DNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays a role in repairing single-strand breaks in duplex DNA in … See more E. coli The E. coli DNA ligase is encoded by the lig gene. DNA ligase in E. coli, as well as most prokaryotes, uses energy gained by cleaving See more DNA ligases have become indispensable tools in modern molecular biology research for generating recombinant DNA sequences. For example, DNA ligases are used with See more Genetic deficiencies in human DNA ligases have been associated with clinical syndromes marked by immunodeficiency, radiation sensitivity, and developmental abnormalities, LIG4 syndrome (Ligase IV syndrome) is a rare disease associated with mutations in … See more The mechanism of DNA ligase is to form two covalent phosphodiester bonds between 3' hydroxyl ends of one nucleotide ("acceptor"), with the 5' phosphate end of another ("donor"). … See more There are at least three different units used to measure the activity of DNA ligase: • Weiss unit - the amount of ligase that catalyzes the exchange of 1 nmole of P from inorganic pyrophosphate to ATP in 20 minutes at 37 C. … See more The first DNA ligase was purified and characterized in 1967 by the Gellert, Lehman, Richardson, and Hurwitz laboratories.
