Dbh polymerase

WebHyperthermophilic archaea offer certain advantages as models of genome replication, and Sulfolobus Y-family polymerases Dpo4 (S. solfataricus) and Dbh (S. acidocaldarius) have been studied intensively in vitro as biochemical and structural models of trans-lesion DNA synthesis (TLS). However, the gen … WebThe resulting plasmid, called p1947, therefore expresses a chimeric polym- erase consisting of the thumb, finger, and palm domains of Dbh and the LF domain of the Dpo4 polymerase (Dbh-LF-Dpo4 ...

WebDbh is a Y-family translesion DNA polymerase from Sulfolobus acidocaldarius, an archaeal species that grows in harsh environmental conditions. Biochemically, Dbh displays a distinctive mutational profile, creating single-base deletion mutations at extraordinarily high frequencies (up to 50 %) in specific repeat sequences. 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 ). ginny meets harry\u0027s parents fanfiction https://h2oattorney.com
