HHsearch alignment for GI: 254780818 and conserved domain: cd05784
>cd05784 DNA_polB_II_exo The 3'-5' exonuclease domain of Escherichia coli DNA polymerase II (PolII) and similar bacterial proteins. PolII is a family-B DNA polymerase. Family-B DNA polymerases contain an N-terminal DEDDy DnaQ-like exonuclease domain in the same polypeptide chain as the polymerase domain, similar to family-A DNA polymerases. This exonuclease domain contains three sequence motifs termed ExoI, ExoII and ExoIII, with a specific YX(3)D pattern at ExoIII. These motifs are clustered around the active site and are involved in metal binding and catalysis. The exonuclease domain has a fundamental role in the proofreading activity of polII. It contains a beta hairpin structure that plays an important role in active site switching in the event of a nucleotide misincorporation. PolII is involved in a variety of cellular activities, such as the repair of DNA damaged by UV irradiation or oxidation. It plays a pivotal role in replication-restart, a process that bypasses DNA damage in a
