The dependence of the specific activity of urease upon the apparent absolute enzyme concentration [PDF]
, 1948 If the activity of an enzyme preparation is determined under conditions in which a further increase in substrate concentration is without demonstrable effect, all other factors being held constant, it is ordinarily assumed that the specific activity of ...
