title: ATPases: common and unique features within a group of enzymes.
abstract: An attempt is made to survey ATPases with respect to features common to all or some of them and features peculiar to each individual enzyme of the group. Clues are presented for a tentative classification of ATPases and a simple system is suggested for the designation of interaction of ATPases with ions which is often used as the main feature of identification of individual ATPases.
