We are referring to the number of RUBISCO active sites measured by immunoquantitation. We are not referring to measured RUBISCO activity. We use this expression to be clear that we are referring to RbcL subunits rather than oligomeric RUBISCO. We have added a parenthetic phrase to make this more clear.
Line 250 – This is estimated number of RUBISCO active sites – or is there evidence all the RUBSCIO you quantify is active?
