摘要：Chlorophyllide a and the apoprotein of myoglobin (Mb) spontaneously form three types of complex. The M (Mr {approx} 3 x 105) and H (Mr [≥] 4 x 106) complexes, but not the L (Mr {approx} 1.7 x 104), display a circular dichroism (CD) spectrum that is highly red-shifted, nonconservative, and very intense--characteristics shared by the CD spectra of reaction center complexes from purple photosynthetic bacteria. At its 710-nm peak, the H complex CD spectrum has a larger magnitude, 0.06 differential absorbance per unit total absorbance, than has been reported for chlorophyll in any medium.
