Proteins possibly used for oxygen sensing in primitive organisms appear to be hemoglobin ancestors. Microbiologist Maqsudul Alam at the University of Hawaii and collaborators at the University of Texas (UT) Southwestern Medical Center at Dallas found a "protoglobin," a hemoglobin progenitor, in Aeropyrum pernix, an aerobic organism that lives in near-boiling salt water. They also found the protoglobin in Methanosarcina acetivorans, an anaerobe found in lake-bottom muck, decaying leaves, and the human gut.
