An unusual enolase isoenzyme, ENO S, was found in human, ram and mouse spermatozoa. This isoenzyme is unique to spermatozoa and distinguished from the somatic enolases ENO 1, ENO 2 and ENO 3 by electrophoretic mobility, high thermostability and ability to undergo structural alteration at high temperatures. The pattern of expression of ENO S during sperm differentiation suggests that this isoenzyme is synthesized relatively late in the presence of a haploid genome.
