The amino acid sequences of a leucine-rich amelogenin polypeptide (LRAP) and a tyrosine-rich amelogenin polypeptide (TRAP), isolated from foetal bovine enamel matrix, were determined. Both LRAP and TRAP occurred in two forms; in each case, one of the molecular species appeared to be shortened at the COOH terminus 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.
测定了从胎牛牙釉质基质中分离出的富含亮氨酸的釉原蛋白多肽（LRAP）和富含酪氨酸的釉原蛋白多肽（TRAP）的氨基酸序列。LRAP和TRAP均以两种形式存在；在每种情况下，其中一种分子形式的COOH末端似乎分别缩短了2个和4个残基。一个显著的发现是，LRAP和TRAP在最初的33个残基上具有相同的序列，但在其余12个氨基酸上几乎完全不同。
