Phosphodiester bond formation by ligase
WebLigases catalyze the formation of phosphodiester bond between 3′OH and 5′phosphate on various substrates such as DNA nicks, DNA fragments with various lengths cohesive … WebBiology questions and answers. 3. (9 points) a) The enzyme DNA ligase catalyzes the formation of a phosphodiester bond between a 3-hydroxyl at the end of one DNA strand and a 5'-phosphate at the end of another strand. Eukaryotic DNA ligase requires ATP for this reaction to activate the 5'-phospghate group.

(a) Nick sealing by DNA ligase occurs through a reaction comprising three steps: ligase adenylylation (step 1), DNA adenylylation (step 2), and phosphodiester synthesis (step 3). (b) The structure of CVLig bound to a nicked duplex DNA. WebThe gap between the two DNA fragments is sealed by DNA ligase, which helps in the formation of phosphodiester bonds. Table summarizes the enzymes involved in prokaryotic DNA replication and the functions of each.
