USER (Uracil-Specific ExcisionReagent) Enzyme (1) generates a single nucleotidegap at the location of a uracil. USER Enzyme is amixture of Uracil DNA glycosylase (UDG) and theDNA glycosylase-lyase Endonuclease VIII. UDGcatalyses the excision of a uracil base, forming anabasic (apyrimidinic) site while leaving the phosphodiesterbackbone intact (2,3). The lyase activityof Endonuclease VIII breaks the phosphodiesterbackbone at the 3´ and 5´ sides of the abasic siteso that base-free deoxyribose is released (4,5).To help select the best DNA assembly method for your needs, please use our Synthetic Biology/DNA Assembly Selection Chart.
