Abstract excerpt
In order to increase the thermal stability and the catalytic properties of pyranose oxidase (P2Ox) from Trametes multicolor toward its poor substrate D-galactose and the alternative electron acceptor 1,4-benzoquinone (1,4-BQ), we designed the triple-mutant T169G/E542K/V546C. Whereas the wild-type enzyme clearly favors D-glucose as its substrate over D-galactose [substrate selectivity...
