Publisher Summary Tyrosyl radicals are found in enzymes that catalyze a wide spectrum of chemical reactions, and their functional importance is well established in class I ribonucleotide reductase (RNR), prostaglandin H synthase (PGHS), and photosystem II (PSII).

Hierarchies of cofactor systems
Journal of Physics A: Mathematical and General, 2002Summary: We assign to any cofactor system a whole hierarchy of such systems. A sufficient condition for their complete integrability is given. The hierarchies admit construction of nontrivial integrable systems from trivial ones.

The exosome is a large protein complex mediating 3'-5' RNA degradation in both nucleus and cytosol of all eukaryotic cells. It consists of nine conserved subunits forming the core complex, which associates with ribonucleolytic enzymes and other cofactors such as RNA-binding proteins or RNA helicases.

Heparin cofactor II (HCII) is a serpin that inhibits thrombin rapidly in the presence of dermatan sulfate or heparin. Both of these glycosaminoglycans bind to HCII and increase the rate of inhibition of thrombin >1000-fold. This review will focus on the biochemistry of HCII and the mechanism by which glycosaminoglycans stimulate its activity.

Biosynthesis of the methanogenic cofactors
2001Our current knowledge of the pathways and genes involved in the biosynthesis of the methanogenic coenzymes methanopterin, coenzyme B, methanofuran, coenzyme F420, and coenzyme M is presented. Proposed reaction mechanisms for several of the novel reactions involved in the pathways are presented.

AIDS: A Noncommunicable Cofactor
JAMA: The Journal of the American Medical Association, 1985To the Editor.— There have been several reports inThe Journalin the past year on the acquired immunodeficiency syndrome (AIDS), including a COUNCIL REPORT. 1 None of them have, however, given consideration to the hypothesis 2 that the access of immunocompetent cells to the allogeneic enzyme transglutaminase (TGase), which is abundant in seminal plasma
