Although relatively rare, the tryptophan residue (Trp), with its large hydrophobic surface, has a unique role in the folded structure and the binding site of many proteins, and its fluorescence properties make it very useful in studying the structures and dynamics of protein molecules in solution.

## Abstract The spleen of the exhypoxic polycythemic mouse was employed as a model system to study the effect of erythropoietin on enzymes that chemically modify nuclear proteins. At selected time intervals after in vivo administration of erythropoietin, acetyltransferase and methyltransferase acti
Poly-irtyrosine absorbs strongly a t 1515 cm.-l, and a band a t this frequency has been found in a number of proteins and has been assigned to the tyrosine residue. The assignment was confirmed by examination of spectra of deuterated proteins, which nsrially exhibit a residual band a t 1513 an.-'.
