Academic career Kadenbach earned a "Diplom" (master's degree) in chemistry at the
Humboldt-Universität zu Berlin in 1959. He spent one year (1960) as
research fellow at the
Wenner-Gren Institute of the
Stockholm University. He obtained his PhD in biochemistry in 1964 at the Institute of Physiological Chemistry,
Philipps-Universität Marburg. The dissertation was entitled "The influence of thyroidhormones in vivo on oxidative phosphorylation and enzyme activities in mitochondria". In 1964 he married Helke Mosner (two children). From 1968 to 1971 he was a teaching and research assistant at the Physiological Chemistry Institute of the
Ludwig-Maximilians-Universität München. In 1971 he was qualified for lecturing at the
Universität Konstanz (
habilitation). The thesis was entitled: “Biosynthesis of cytochrome c”. From 1971–1973 he became "Oberassistent" (assistant professor) at the Laboratory of Biochemistry at the
Eidgenössischen Technischen Hochschule Zürich, Switzerland. In 1973 he became a professor of biochemistry at the Fachbereich Chemie, Philipps-Universität Marburg. His formal retirement was in 1998. From 2003–2013 he continued his research on regulation of cytochrome c oxidase at the Biomedizinisches Forschungszentrum (BMFZ) within the Klinikum of the Philipps-Universität Marburg.
Fields of research Kadenbach studied the
mitochondrial phosphate carrier and found its essential requirement for
cardiolipin. Subsequent studies concentrated on the
protein structure and function of the mitochondrial
cytochrome c oxidase. He discovered the occurrence of tissue-specific and developmental-specific
protein isoforms. Defective cytochrome c oxidase activity was found in
mitochondrial diseases and in human
muscle cells with increasing age. Ten specific binding sites for
ADP or
ATP were identified in mammalian cytochrome c oxidase, which regulate the H+/e-
stoichiometry of
proton pumping, and the
allosteric inhibition of activity, depending on the ATP/ADP ratio.
Stress-dependent reversible
dephosphorylation of cytochrome c oxidase suggests formation of reactive oxygen species. A hypothesis on the cause of
oxidative stress, aging and disease was published by Kadenbach in 2013.
