WebThe DNA duplex is accommodated in a positively charged groove of the thumb domain, as observed in other B-family DNA polymerases (Fig. 2). For B-family DNA polymerases, proliferating cell nuclear antigen (PCNA) or PCNA-like … Web23 Apr 2014 · Y-Family DNA polymerases specialize in translesion synthesis, bypassing damaged bases that would otherwise block the normal progression of replication forks. Y-Family polymerases have unique structural features that allow them to bind damaged DNA and use a modified template base to direct nucleotide incorporation. Each Y-Family … WebDNA polymerases function in DNA replication, repair, recom-bination and translesion synthesis. Currently, 15 DNA polymer-ase genes have been identified in human cells, belonging to four distinct families.
