Site-directed mutagenesis of motif III in PcrA helicase reveals a role in coupling ATP hydrolysis to strand separation.

Motif III is one of the seven protein motifs that are characteristic of superfamily I helicases. To investigate its role in the helicase mechanism we have introduced a variety of mutations at three of the most conserved amino acid residues (Q254, W259 and R260). Biochemical characterisation of the r...
