Apparent steady-state kinetic constants of TmP2O wild-type and mutants with D-glucose or D-galactose as electron donor, and O2 (air) under saturation as electron acceptor.

aSince H167A was not designed to specifically improve galactose turnover, but to slow down flavin reduction during the reductive half-reaction, the kinetic constants for H167A were not determined. The mutant was included since it is a close structural mimic of the wild-type when sugar binding is concerned. Its purpose is therefore mainly for structural comparisons.
