Result: All tested
RTs showed similar or increased catalytic efficiencies (measured as the ratio kcat/Km) in comparison with the O_WT
RT, and the mutant enzyme
V75I (O_
V75I), as well as with the BH10_WT
RT.
Result: Although position +149 could be considered as a common hot spot location for both mutant
RTs, identified errors were one-nucleotide deletions in the case of O_
V75I/
D443N RT and base substitutions (mostly G T mutations) in the case of O_
V75I/
E478Q RT.
Method: The
Q151M complex of mutations was defined as
Q151M alone or in combination with one or more of the following mutations:
A62V,
V75I,
F77L, and
F116Y.
