Conformational studies of hemoglobins using intrinsic fluorescence measurements.

Abstract

Front face fluorometry allows for the detection of intrinsic fluorescence in intact hemoglobins, and we have been able to assign the origin of this emission in Hb A to the tryptophan at beta 37 (Hirsch, R. E., Zukin, R. S., and Nagel, R. L. (1980) Biochem. Biophys. Res. Commun. 93, 432-439). We now report that this fluorescence in hemoglobin is sensitive to… (More)
