Abstract
The occurrence and characteristics of Ca2+ and anion-sensitive ATPase activities were studied in a plasma membrane fraction (PMF) isolated f rom crab Cyrtograpsus angulatus gills, An ATPase activity, stimulated by Ca2+ and sensitive to vanadate, is present in PMP. The highest acti vity was found at 8 mM Ca2+. The optimal pH was 9.00, PMF also contain ed an ATPase activity stimulated by either Cl- or HCO3- or Cl- plus HC O3- which was Mg2+-dependent.
