Abstract

The abnormal hemoblobin designated as Hb M Oldenburg and already characterized as alpha 2 (72,87 or 89)His replaced by Tyr beta 2 was further identified by isolation, amino acid analysis and automated sequencing of the altered tryptic peptide alpha TIX. In this peptide the histidine in the position 87 is replaced by a tyrosine reside. Thus Hb M Oldenburg has to be described as alpha 2 87(F8)His replaced by Tyr beta 2 and is, therefore, identical with the mutant hemoblobins M Iwate and M Kankakee.

摘要

被命名为Hb M奥尔登堡的异常血红蛋白,已被鉴定为α2(72、87或89位)组氨酸被β2位酪氨酸取代,通过对改变后的胰蛋白酶肽αTIX进行分离、氨基酸分析和自动测序进一步得到确认。在该肽段中,87位的组氨酸被一个酪氨酸残基取代。因此,Hb M奥尔登堡必须被描述为α2 87(F8)组氨酸被β2位酪氨酸取代,所以它与突变血红蛋白M岩手和M坎卡基相同。
