The amino acid sequences of the myoglobins of two rodents, the casiragua and the house mouse, have been determined. The myoglobin of casiragua differs from that of viscacha (another hystricomorph) at 6 positions. Mouse myoglobin differs from that of mole-rat (another myomorph) at 17 positions, whereas casiragua and mouse differ at 22 positions. Mouse myoglobin possesses several features unique among all known myoglobins (Gly 31, Cys 66, Thr 74 and Glu 113) and one substitution unique among known mammalian myoglobins (Glu 53).
已测定了两种啮齿动物——南美栗鼠和家鼠的肌红蛋白的氨基酸序列。南美栗鼠的肌红蛋白与绒鼠(另一种豪猪亚目动物)的肌红蛋白在6个位置上存在差异。家鼠的肌红蛋白与鼹形鼠(另一种鼠形亚目动物)的肌红蛋白在17个位置上存在差异,而南美栗鼠和家鼠的肌红蛋白在22个位置上存在差异。家鼠的肌红蛋白具有一些在所有已知肌红蛋白中独有的特征(甘氨酸31、半胱氨酸66、苏氨酸74和谷氨酸113)以及一个在已知哺乳动物肌红蛋白中独有的替换(谷氨酸53)。
