© 2006 The Author(s)All GyrA mutants were mixed with GyrB at an equal molar concentration (1.0 μM) at 25°C for ∼20 min, and incubated with 75 ng of 240 bp DNA in 20 μl DNA-binding buffer. Lane 1, DNA sample without any proteins; lane 2, GyrA alone; lanes 3–9, wild-type gyrase, E514A, Y577A, D669A, R691A, G729W, R745A, respectively plus DNA and GyrB; lane 10, GyrB only.
