The identity of two other reported binding proteins from sarcoplasmic reticulum is in doubt. Tropocalcin, isolated by Benson and Han may be identical to calsequestrin (78) and cardioglobulin-C (79) may be identical to the calcium transport ATPase (80), although the cardioglobulin has also been demonstrated in blood plasma (79).

There is good evidence that the calcium-transporting ATPase can be used as a marker enzyme for the plasma membrane of Anabaena. So far, only a transport function but no substantial electron transport function can be attributed to this membrane, unlike findings with Anacystis (Peschek et al. 1983) In vivo the calcium pump probably excretes calcium from the cell, since calcium is transported away from the side of ATP hydrolysis (into the isolated vesiclesX.
