Abstract

Here we describe the identification of a γ-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, (28000-30000) and its amino acid composition.
