Rainbow trout myoglobin (Mb) is characterized by an unusually low affinity for oxygen, having a P(50) of 4.92±0.29 mm Hg at 25 °C which is the highest ever reported for any vertebrate Mb at the same temperature (Helbo and Fago, (2011) Am. J. Physiol. Regul. Integr. Comp. Physiol. 300, R101-R108). In order to gain insight into the structural factors of the heme pocket that may be important determinants for this atypical oxygen affinity, we have carried out an electronic absorption and resonance… CONTINUE READING
