use of the heme enzyme for the rapid, in situ generation of O2 at concentrations far exceeding 2 mM in coupled enzyme reaction systems to study O consumption or O2 involving reaction steps. Catalytic concentrations of chlorite O2-lyase can be used to initiate the reaction of an O2-utilizing (metallo)enzyme by rapid mixing with the highly soluble, non-volatile ClO2, rather than with the sparingly soluble, gaseous O2, e.g. activation of the beta2 subunit of class Ic ribonucleotide reductase from Chlamydia trachomatis by mixing its MnII/FeII complex with ClO2- in the presence of chlorite O2-lyase, overview |
