1.1.3.6 | E311D |
mutations of Glu311 cause a switch in the basic kinetic mechanism of the reaction of reduced cholesterol oxidase with dioxygen: wild-type cholesterol oxidase shows a saturation behavior with increasing oxygen concentration, while for Glu311 mutants a linear dependence is found that is assumed to reflect a simple second order process |

1.1.3.6 | E311L |
mutations of Glu311 cause a switch in the basic kinetic mechanism of the reaction of reduced cholesterol oxidase with dioxygen: wild-type cholesterol oxidase shows a saturation behavior with increasing oxygen concentration, while for Glu311 mutants a linear dependence is found that is assumed to reflect a simple second order process |

1.1.3.6 | E361A |
site-directed mutagenesis, the mutant shows no dehydrogenase activity |

1.1.3.6 | E361Q |
H447Q mutant shows wild-type activity in isomerization, kcat for oxidation reaction is reduced 120fold, Km increases 2fold compared to wild-type, E361Q mutant has no isomerization activity, kcat is 30fold slower than for wild-type, Glu361 may therefore act as general base in oxidation reaction |

1.1.3.6 | E361Q |
turnover number for cholesterol is decreased 31.4fold compared to wild-type enzyme, 1.8fold increase in Km-value for cholesterol compared to wild-type enzyme |
