ADAPTIVE SCHEMES FOR MULTICARRIER TRANSMISSION SYSTEM WITH MB-OFDM MODULATION
Plant hemoglobins diverged from worm hemoglobins ?1500 million years ago, although there are little remaining structural similarities. Both, however, evolved Cys residues in the distal pocket that are not present in microbial flavohemoglobins. The perienteric hemoglobin of Ascaris is an NO-primed deoxygenase that employs NO to detoxify O2. In this case, NO is transferred oxidatively from the heme to a critical Cys within the heme pocket where it is ready to react with O2. We therefore suggest that distal Cys residue(s)...
