Biosynthesis of Rat Enamel Matrix Components
in vivo
S. Sasaki, H. Shimokawa, K. Tanaka
The biosynthesis of enamel matrix components of developing rat incisors was in investigated by measuring the incorporation of
3
H-proline,
32
P-phosphate, and
35
S-sulfate in vivo.
3
H- and
32
P-radioactivity was found in what seemed to be a prototype of enamel proteins. Subsequent shifts in other protein and peptide fractions were observed,
35
S was also incorporated into components other than the above-mentioned proteins.
