The complete amino acid sequence of a beta-galactoside-binding lectin from human placenta was determined at protein level. The lectin consists of 134 amino acids and its N-terminal alanine is blocked with acetate. The lectin shows about 50% similarity with chick 14K lectin, which was the first vertebrate beta-galactoside-binding lectin completely sequenced. Only 14 residues proved to be different from those of rat lung lectin, the sole mammalian lectin of which the complete sequence has been reported.
在蛋白质水平上确定了来自人胎盘的β-半乳糖苷结合凝集素的完整氨基酸序列。该凝集素由134个氨基酸组成，其N端丙氨酸被乙酸酯封闭。该凝集素与鸡14K凝集素显示出约50%的相似性，鸡14K凝集素是第一个完全测序的脊椎动物β-半乳糖苷结合凝集素。结果表明，只有14个残基与大鼠肺凝集素不同，大鼠肺凝集素是唯一已报道完整序列的哺乳动物凝集素。
