Phosphodiester bonds ligase
WebDNA ligases catalyze the formation of a phosphodiester bond between DNA single strands in the duplex form (Fig. 2.1 ). The covalent linkage of the 5′-P group of one chain with the adjacent 3′-OH group of another is coupled with the pyrophosphate hydrolysis of the cofactor ATP or NAD. WebA phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. An example is found in the linking of two pentose (5 carbon …
