The primary sequences of the myoglobins of two rodents (the South American viscacha and the Mediterranean mole rat) have been determined. Both myoglobins exhibit one polymorphism. The two rodent sequences have been compared with each other and with other known myoglobins. The myoglobin of the viscacha is similar to those of the diving mammals and penguin in having a high arginine content. Among mammalian sequences, the arginines at positions 77 (in one of the viscacha myoglobins) and 79 have been found only in the myoglobin from viscacha. Mole rat myoglobin has a lysine at position 31, where arginine or serine is found in all other known vertebrate myoglobins.
