Rat spermatozoa from the cauda epididymidis were found to have a lower activity of the surface ATPase than the spermatozoa from the caput region. The enzyme from spermatozoa of both regions had the same Michaelis constant (K(m)) for ATP of 5x10 -4 M. It was partly inhibited by ouabain and fluoride,...
