Hi

A spread of energies for the Selenium K edge from selenomethionyl labelled
proteins have been reported in the literature (see for example Hendrickson
and Ogata in Methods in Enzymology Vol 276, 494, 1997).  To what extent does
this spread represent real differences rather than errors in the calibration
of the monochromator?  Does an oxidized selenomethionine have a
significantly different spectrum?
