1. Proton, Electron, and O2 transfer in Cytochrome c Oxidase
Abstract : In mitochondria and aerobic bacteria energy conservation involves electron transfer through the membrane-bound protein of the respiratory chain to oxygen. Cytochrome c oxidase (CcO) catalyzes the reduction of oxygen to water. Part of the energy released in this reaction is used to pump protons across the membrane. READ MORE

2. Modulation of cytochrome c release by mitochondrial redox status and caspase-2
Abstract : The release of cytochrome c is an important event during apoptosis, induced by diverse stimuli. Our laboratory has previously proposed that cytochrome c release occurs via a two-step process, involving the detachment of the hemoprotein from its binding to the inner mitochondrial membrane, followed by its release into the cytosol through pores in the outer mitochondrial membrane - an event that is usually triggered by proapoptotic Bcl-2 family proteins, such as Bid, Bax and Bak.

3. Active Transport of Ions across Biomembranes : A Kinetic Study of Cytochrome c Oxidase Reconstituted into Phospholipid Vesicles
Abstract : Ion transport across membranes is of uttermost importance for us. It is the foundation for signaling of various kinds e.g. in the nerve-system. READ MORE

4. Prokaryotic respiratory supercomplexes : Studies of interactions between complexes III and IV
Abstract : Respiratory processes for cellular energy conversion are carried out by the membrane-associated enzymes of the electron transfer chain (ETC). In recent years there has been emerging data showing that the members of the ETC organize into higher-level assemblies called supercomplexes (SCs) whose functional relevance is not yet fully understood.

5. Structural studies of ba3-type cytochrome c oxidase using serial crystallography and X-ray absorption spectroscopy
Abstract : Cytochrome c oxidase (CcO) catalyses the reduction of molecular oxygen to water while the energy released in this process is used transport protons “up-hill” across an energy transducing biological membrane, creating a proton-motive force for ATP synthesis. Given its key role in energy transduction in organisms, proton pumping has been extensively studied across species. READ MORE
