Adult chicken hemoglobin is heterogeneous and contains two major components, AI and AII (1). The amino acid sequence of the alpha chain of the AI component from white leghorns (small A type) was determined and compared with that of the alpha chain of the AII component, previously determined by the authors (2). An unexpectedly large difference of 65 amino acids was found between these two chains.
成年鸡血红蛋白具有异质性,包含两种主要成分,即AI和AII(1)。已确定白来航鸡(小A型)AI成分的α链氨基酸序列,并将其与作者先前确定的AII成分的α链氨基酸序列进行了比较(2)。结果发现这两条链之间存在65个氨基酸的意外巨大差异。
