Abstract
Primary structure of beta-chain of pigeon is presented. It was determined by amino acid sequence analysis of intact beta-chain and its peptides obtained by the enzymatic and chemical cleavage. Comparison of amino acid sequence of the chain with other available data shows beta 14 Ile, beta 61 Lys, and beta 113 Ile as residues specific to pigeon. One important replacement at alpha 1 beta 1 contact is beta 55 Met----Ser.
摘要
本文展示了鸽子β链的一级结构。它是通过对完整β链及其经酶切和化学裂解得到的肽段进行氨基酸序列分析确定的。将该链的氨基酸序列与其他现有数据进行比较，发现β14异亮氨酸、β61赖氨酸和β113异亮氨酸是鸽子特有的残基。α1β1接触处的一个重要替换是β55甲硫氨酸替换为丝氨酸。
