Dbh polymerase
WebJul 8, 2015 · The dinB homolog (Dbh) is a member of the Y-family of translesion DNA polymerases, which are specialized to accurately replicate DNA across from a wide variety of lesions in living cells. Lesioned bases block the progression of high-fidelity polymerases and cause detrimental replication fork stalling; Y-family polymerases can bypass these … WebOct 5, 2001 · The authors suggest that Dbh may not operate by the type of induced-fit mechanism proposed for replicative polymerases such as the T7 enzyme, Taq polymerase, and mammalian polβ ( Kunkel and Bebenek 2000 ). This suggestion is supported by comparing the Dpo4 structure (with DNA) with that of Dbh (without DNA) ( Figure 1B ).
