Abstrakt: Here we describe the identification of a gamma-carboxyglutamic acid-containing protein in human spermatozoa. After thermal decarboxylation the protein is a good substrate for vitamin K-dependent carboxylase from various origins. A quick purification procedure for the decarboxylated protein is presented and in a preliminary characterization we have established its Mr (28 000-30 000) and its amino acid composition.
