1. Two phosphoproteins have been isolated from maturing egg yolks of Kinixys erosa by a combination of gel filtration and anion exchange chromatography. 2. The two proteins, TEYP-2 and TEYP-3, have View the MathML source of 68,000 and 29,000, respectively. 3 3. They have a phosphorus content of 5.5 and 30.0 μmol Pi/mg protein, respectively. 4. Serine accounts for 45 and 16.5% of the amino acid residues. 5. They are both glycoproteins and both have lysine as the View the MathML source amino acid residue.
