title: New structural clues to substrate specificity in the "ubiquitin system".
abstract: A 2.5 A crystal structure of a complex between the SUMO-conjugating enzyme Ubc9 and a protein substrate has yielded fresh insight into the specificity of protein modification by SUMO and other ubiquitin-like proteins.
