Helicase activity of the extended DbpA in presence of various RNA–DNA chimeras. (A) The RNA–DNA molecules used in the helicase experiments in (B). (B) Helicase activity of the 23 amino acid extended DbpA was measured in presence of molecule A:X (filled square), B:X (empty square), C:X (triangles), D:X (diamond), E:X (empty circle) plus 5 mM ATP. The data are representative of one experiment. The averages from multiple experiments and the standard deviations are shown in Table 2.
