The nuclease assay was adapted from ().In short, the reactions were typically performed in a volume of 20 μl containing 10 mM Tris-HCl (pH 7.5), 1 mM DTT, 0.1 mg/ml BSA, 10 mM MgCl 2, 25 fmol DNA substrate and varying amounts of MGME1.Reactions were incubated at 37°C for 30 … WebbAbstract. DNA polymerase III holoenzyme (pol III HE) is responsible for bacterial chromosomal DNA replication, along with the helicase and primase, at the replication fork. Pol III HE is a multi-subunit complex, in which pol III core possesses the polymerization and proofreading activity and the clamp loader and sliding clamp provide processivity.
