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]

Publication Abstract from PubMed
Alpha,beta-difluoromethylene deoxynucleoside 5'-triphosphates (dNTPs, N = A or C) are advantageously obtained via phosphorylation of corresponding dNDP analogues using catalytic ATP, PEP, nucleoside diphosphate kinase, and pyruvate kinase. DNA pol beta K(d) values for the alpha,beta-CF(2) and unmodified dNTPs, alpha,beta-NH dUTP, and the alpha,beta-CH(2) analogues of dATP and dGTP are discussed in relation to the conformations of alpha,beta-CF(2) dTTP versus alpha,beta-NH dUTP bound into the enzyme active site.
