“…It is indeed remarkable that all proteins for which specific interactions with halothane have been demonstrated [19] process functionally important binding sites for purine nucleotides; examples are microtubules [20], glutamate dehydrogenase [4], calcium-transport ATPases [5,21,22] and phosphoryl transferases [10,23]. This aspect could facilitate the search for the principal halothane receptors in normal anaesthesia.…”
