DNA Polymerase Beta E295K with Spiroiminodihydantoin in Templating Position

Template:ABSTRACT PUBMED 24649945

Function

[DPOLB_HUMAN] Repair polymerase that plays a key role in base-excision repair. Has 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity that removes the 5' sugar phosphate and also acts as a DNA polymerase that adds one nucleotide to the 3' end of the arising single-nucleotide gap. Conducts 'gap-filling' DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases.[1] [2] [3] [4]

About this Structure

4ppx is a 4 chain structure with sequence from Human. Full crystallographic information is available from OCA.
