Isothermal Titration Calorimetry Uncovers Substrate Promiscuity of Bicupin Oxalate Oxidase
… ethylbenzthiazoline-6-sulphonic acid) and by membrane inlet mass spectrometry. Coupled enzyme assays often confound data interpretation. Isothermal titration calorimetry (ITC) measures heat changes that occur during a reaction. Therefore, ITC can measure reaction rates where both the …

Hydrogen Peroxide Inhibition and Inactivation of Bicupin Oxalate Oxidase
… on the CsOxOx catalyzed oxidation of oxalate. Membrane inlet mass spectrometry (MIMS) was used to directly measure initial rates of carbon dioxide formation and oxygen consumption in varying initial concentrations of hydrogen peroxide. This work demonstrates that hydrogen peroxide is both a …

Probing the Mechanism of Oxalate Decarboxylase
… catalytic mechanism of OxDC. The application of membrane inlet mass spectrometry (MIMS), electronic paramagnetic resonance (EPR) spectroscopy and kinetic isotope effects (KIEs) provided more detailed information about the mechanism. Mn(III) was identified and characterized under acidic conditions …

The role of dissolved gas fluxes on the biogeochemical evolution of nutrient cycles in lakes.
… to 1) estimate ecosystem O2 metabolism using membrane inlet mass spectrometry, 2) study N2 accumulation and drawdown in a stratified and well-mixed reservoir, and 3) measure sediment N and P dynamics in differing redox conditions. Taken together, these projects have continued adding to the …

Photoprotection and chloroplast regulation in the green algae Chlamydomonas reinhardtii
Absorbed light energy in excess of a cell's photosynthetic capacity can lead to production of reactive oxygen species (ROS) causing cell damage and death. Plants and algae have evolved conserved photoprotective responses that, at the level of light harvesting, are collectively measured as …
