Phosphodiester bond formation by ligase
WebT4 DNA Ligase catalyzes the formation of phosphodiester bonds between juxtaposed 5' phosphate and 3' hydroxyl termini in blunt-end or sticky-end dsDNA. This product also can catalyze the ligation of RNA and ssDNA or RNA strands in double strands, but it cannot catalyze the ligation of whole single-stranded nucleotides. WebMay 13, 2008 · Fig. 1. CVLig and its AMP-dependent reaction reversal. (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.

(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.
WebDNA ligase is an important enzyme used in molecular biology techniques. It functions as a molecular glue to join nucleotides by forming phosphodiester bonds between nucleotides. The phosphodiester bonds are formed between the 3’ hydroxyl end of the sugar moiety and the 5’ end phosphate group. DNA ligase is WebLigase, on the other hand, is an enzyme that catalyzes the formation of a phosphodiester bond between two adjacent nucleotides, joining them together. By using endonucleases to cut DNA at specific recognition sites and ligase to join the cut ends of two different DNA molecules, researchers can create recombinant DNA molecules with desired ...
