✦ Synopsis
The ring-tailed lemur, Lemur catta, shows a two-component hemoglobin phenotype after alkaline electrophoresis. A difference in the amino acid sequence of the isolated a-globins was observed at position 15 (a I-Gly, a II-Lys) and can account for the electrophoretic pattern of two hemoglobin components. Only one other amino acid difference was found in the sequence of the two globin chains: a neutral substitution occurs at position 53 (a I-Gly, a 11-Ala). The complete primary structures of the duplicated a-globin chains of Lemur catta are presented.
