among the different strains analyzed this enzyme was practically absent selectively from the 'non-discharge ' mutant nd9-28 degrees c ( from j. beisson ) : if cultured at a permissive temperature ( 18 degrees c ) , this strain showed identical values of calmodulin-stimulated ca2+-atpase activity as wild-type cells ( 7s ) or strains with mutations which do not affect exocytosis performance .
