Abstract
cDNA for rat alpha-lactalbumin has been cloned in bacterial plasmid, and its sequence has been analyzed. The DNA sequence analysis shows that rat alpha-lactalbumin has 17 extra residues beyond the COOH terminus of the alpha-lactalbumin isolated and sequenced to date from other species. The predicted COOH-terminal sequence is hydrophobic and proline rich and bears some resemblance to beta-casein sequences.
摘要
大鼠α-乳白蛋白的互补DNA（cDNA）已被克隆到细菌质粒中，并对其序列进行了分析。DNA序列分析表明，与迄今从其他物种中分离并测序的α-乳白蛋白相比，大鼠α-乳白蛋白在COOH末端有17个额外的残基。预测的COOH末端序列具有疏水性且富含脯氨酸，与β-酪蛋白序列有一些相似之处。
