测定了从胎牛釉质基质中分离得到的一种富亮氨酸淀粉原蛋白多肽（LRAP）和一种富酪氨酸淀粉原蛋白多肽（TRAP）的氨基酸序列。LRAP和TRAP以2种形式出现；在每种情况下，其中一种分子在COOH末端分别缩短了2个和4个残基。一个惊人的发现是LRAP和TRAP在前33个残基上有相同的序列，但在剩下的12个氨基酸上却几乎完全不同。
The amino acid sequences of a leucine-rich amelogenin polypeptide (LRAP) and a tyrosine-rich amelogenin polypeptide (TRAP), isolated from fetal bovine enamel matrix, were determined. LRAP and TRAP occurred in 2 forms; in each case, one of the molecular species is shortened at the COOH terminal by 2 and 4 residues, respectively. A striking finding was that LRAP and TRAP had identical sequences for the first 33 residues, but were almost completely different for the remaining 12 amino acids.
