title: [Study of a non-collagen protein fraction of dentin during minerlization].
abstract: A protein fraction of mineralizing porcine dentine was analysed after E.D.T.A. demineralization. This fraction of heterogeneous composition had a high content of phosphorus. Its acid character, deductible from the amino acid analysis, was confirmed by electrophoresis. After Sephadex gel filtration, five fractions were obtained. They could be characterized by amino acid analysis and phosphorus dosage. Two fractions contained phosphorus and were very rich in aspartic acid and serine. The three other fractions were characterized by their very high content of glycine.
