Which DNA polymerases are used for DNA-repair in eukaryotes?
There are five well-characterized nuclear DNA polymerases in eukaryotes (DNA polymerases alpha, beta, delta, epsilon and zeta) and this short review summarizes our current knowledge concerning the participation of each in DNA-repair. The three major DNA excision-repair pathways involve a DNA synthesis step that replaces altered bases or nucleotides removed during repair. Base excision-repair re...
متن کاملError-prone repair DNA polymerases in prokaryotes and eukaryotes.
DNA repair is crucial to the well-being of all organisms from unicellular life forms to humans. A rich tapestry of mechanistic studies on DNA repair has emerged thanks to the recent discovery of Y-family DNA polymerases. Many Y-family members carry out aberrant DNA synthesis-poor replication accuracy, the favored formation of non-Watson-Crick base pairs, efficient mismatch extension, and most i...
متن کاملDatabase of DNA polymerases.
The DNA Polymerase Database (Polbase) is intended to compile the wealth of existing DNA polymerase information from public and private records into an open, searchable database.
متن کاملEukaryotic DNA Polymerases
Themajor function ofDNApolymerases is to replicate the genome and thus to allow transmission of genetic information fromone generation to the next. In eukaryotic cells, this takes place during a discrete period (S phase) of interphase, and replicated chromosomes are subsequently segregated to daughter cells during mitosis. As well as replicating DNA, polymerases help to maintain the integrity o...
متن کاملViral DNA Polymerases
Because many viruses are readily amenable to molecular, genetic, and biochemical analyses, and because the replication of certain viruses has been the target of antiviral drug development, a wealth of information has accumulated regarding the structure, functions, properties, and regulation of eukaryotic viral DNA polymerases. Viral DNA polymerases have interesting similarities with eukaryotic ...
