Abstract
RECENT work by Weber1â3 has shown that the ultraviolet fluorescent spectra of globular proteins differ from those predicted for the summation of the independent contributions of their aromatic amino-acid constituents. Those examples investigated which contained tyrosine, but no tryptophan, showed a tyrosine emission spectrum, but with a reduced quantum yield. Those containing both tyrosine and tryptophan showed an emission spectrum predominantly resembling that of tryptophan alone, with an emission maximum in the range 320â350 mµ. The present communication will be concerned solely with proteins of the second category.
