DnaQ
dnaQ is a gene found in many bacteria that encodes the epsilon subunit of DNA polymerase III, the main enzyme responsible for chromosomal DNA replication. In Escherichia coli, dnaQ is also known as mutD, a name that reflects its role in maintaining replication fidelity.
The primary function of the DNA polymerase III epsilon subunit is 3′ to 5′ exonuclease proofreading. As
Genetically, dnaQ is conserved across many bacterial species, and its proper function is important for maintaining
In summary, dnaQ encodes the epsilon subunit of DNA polymerase III, providing essential 3′ to 5′ proofreading
