The aminoethylated beta polypeptide chain in AII component from the hemoglobin of adult chicken was digested with trypsin [EC 3.4.21.4] and the resulting peptides were separated and purified by ion exchange chromatography, paper chromatography, and gel filtration. Eighteen tryptic peptides, which were nonoverlapping, accounted for all of the amino acid residues in the beta polypeptide chain. The amino acid sequences of the tryptic peptides were established by a combination of enzymatic digestion and subtractive Edman degradation.
用胰蛋白酶[EC 3.4.21.4]消化成年鸡血红蛋白AII组分中的氨乙基化β多肽链,所得肽段通过离子交换色谱法、纸色谱法和凝胶过滤法进行分离和纯化。18个不重叠的胰蛋白酶肽段涵盖了β多肽链中的所有氨基酸残基。通过酶消化和减法埃德曼降解相结合的方法确定了这些胰蛋白酶肽段的氨基酸序列。
