1923 Jrnl. Chem. Soc. 123 828 The two forms of the ion are tautomeric..; but they yield protomeric hydrides, and isomeric derivatives with radicles such as methyl and ethyl.

1968 Jrnl. Amer. Chem. Soc. 90 1575/1 In the cases of the heteroaromatic isomers, the protomeric equilibrium has been..found to favor the amide in solution.

1994 Chem. Physics Lett. 220 129/1 Protomeric tautomerism of heterocyclic molecules is a subject of continuing theoretical and experimental studies, prompted..by the biological implications of such tautomerism on base pair interactions.

1966 Proc. National Acad. Sci. U.S.A. 56 1756 It is clear that ATP-Mg or malonyl CoA promote the dissociation of acetyl CoA carboxylase into protomeric units.

1988 Nature 24 Nov. 403/2 Nearly all of the protomeric contacts are provided by the β subunits that form a hollow inner shell bounding a central cavity of about 50 Å in diameter.
