Crystal structures of BocLys bound to PylRS. (a, b) Stereoviews of the previously determined form 1 (a) and the present form 2 (b) structures of BocLys-AMPPNP-bound PylRS(c270). (c) Superposition of the form 1 (blue white) and form 2 (light green) structures. (d) The Fo - Fc OMIT electron-density map (contoured at 4[sigma]) of the unusually bent enzyme-bound BocLys in form 2.  [article HTML]
