Evolutionary implications: myoglobin-like proteins found in
ancient microorganisms
UH researchers find myoglobin-like proteins in ancient microorganisms A University of Hawaii
research team has discovered a new class of myoglobin-like proteins in ancient microorganisms. In
animals, myoglobin (found in muscle) and its close relative hemoglobin (the main protein in the red
blood cell) play an essential role in oxygen transport and storage. The newly identified proteins may
be the evolutionary ancestors of proteins involved in oxygen sensing as well as transport and storage.
The findings, which appear in the Feb. 3 issue of the British journal Nature, add another piece to the
puzzle of when and how life arose and evolved on earth.
The research team that made this discovery is headed by Maqsudul Alam, associate professor of
microbiology, and Randy Larsen, associate professor of chemistry, both of the University of Hawaii at
Manoa's College of Natural Sciences. Their team cloned the genes expressing these proteins, which
