The mechanism of alkali resistance in hemoglobin Rainier, an adult human hemoglobin variant (β 145 tyrosine → histidine), has been investigated. Web9 mei 1994 · In Hemoglobin Rainier, an intrasubunit disulfide is formed between the wild type F9(93)β Cysteine and the cysteine introduced by replacement of the Tyr at HC2(145)β. Greer, et al., Nature [New Biology], 230:261-264 (1971). Hemoglobin Nunobiki (β 141 Drg Cys) also features a non-polymerizing cysteine substitution.
