In molecular biology, the δ (delta) subunit of DNA polymerase III is encoded by the holA gene in E. coli and other bacteria. Along with the γ, δ', χ, and ψ subunits that make up the core polymerase, and the β accessory proteins, the δ subunit is responsible for the high speed and processivity of polIII.[1][2]
