Table 1 Kinetics of Danio pol β in the presence of Mg2+ or Mn2+

From: Characterization of DNA polymerase β from Danio rerio by overexpression in E. coli using the in vivo/in vitro compatible pIVEX plasmid

Metal ion Substrate Km [μM] kcat [min-1] kcat/Km × 103 [μM-1 min-1]
Mg2+ dTTP 14.69 0.74 0.05
Mn2+ dTTP 1.32 0.58 0.43
