Coenzyme nature

In accordance with the recommendation of the Commission of the International Union of Biochemistry [R. H. S. Thompson, Classification and nomenclature of enzymes and coenzymes, Nature 193, 1227 (1902)] the terms NAD and NADP have been used instead of DPN and TPN, except in Fig. 4. The generic term nicotinamide nucleotides is used with the same significance as pyridine nucleotides.

In retrospect, it is quite remarkable that at the same time when Chatt s group performed their studies on organometallic compounds with phosphine ligands, Dorothy Crowfoot-Hodgkin completed her work on the structure of vitamine B12, for which she was awarded the Nobel Prize for Chemistry in 1964. As far as we presently know, vitamine BJ2 is the only natural product containing a transition metal-carbon cr-bond [see P. G. Lenhert, and D. Crowfoot-Hodgkin, Structure of the 5,6-Dimethylbenzimidazolylcobamide Coenzyme, Nature 192,937-938 (1961)].
