Ca2+ the enzyme in testicular fluid has an absolute requirement for either Co2+, or Mn2+, Mg2+ and ca2+. The activity is stimulated by the cations in the above order. The enzyme from cauda epididymal fluid has an absolute requirement for Mn2+ or Ca2+, with Co2+ and Mg2+ being ineffective Rattus norvegicus
