Chemical magnetoreception: bird cryptochrome 1a is excited by blue light and forms long-lived radical-pairs. [PDF]
PLoS ONE, 2007 Cryptochromes (Cry) have been suggested to form the basis of light-dependent magnetic compass orientation in birds. However, to function as magnetic compass sensors, the cryptochromes of migratory birds must possess a number of key biophysical ...

Refining the reaction mechanism of O2 towards its co-substrate in cofactor-free dioxygenases [PDF]
, 2016 Cofactor-less oxygenases perform challenging catalytic reactions between singlet co-substrates and triplet oxygen, in spite of apparently violating the spin-conservation rule.

Reactions of electron-transfer flavoprotein and electron-transfer flavoprotein: ubiquinone oxidoreductase [PDF]
Biochemical Journal, 1987 Electron-transfer flavoprotein:ubiquinone oxidoreductase (ETF-Q oxidoreductase) catalyses the re-oxidation of reduced electron-transfer flavoprotein (ETF) with ubiquinone-1 (Q-1) as the electron acceptor. A kinetic assay for the enzyme was devised in which glutaryl-CoA in the presence of glutaryl-CoA dehydrogenase was used to reduce ETFox.

ESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.
