Secondary Accession Numbers
  • 6238
Name DNA polymerase beta
Synonyms Not Available
Gene Name POLB
Protein Type Unknown
Biological Properties
General Function Involved in DNA binding
Specific Function 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.
Pathways
  • Base excision repair
  • Human T-cell leukemia virus 1 infection
  • Viral carcinogenesis
Reactions
Deoxynucleoside triphosphate + DNA(n) → Pyrophosphate + DNA(n+1) details
