title = "A conserved asparagine has a structural role in ubiquitin-conjugating enzymes",
abstract = "It is widely accepted that ubiquitin-conjugating enzymes contain an active site asparagine that serves as an oxyanion hole, thereby stabilizing a negatively charged transition state intermediate and promoting ubiquitin transfer. Using structural and biochemical approaches to study the role of the conserved asparagine to ubiquitin conjugation by Ubc13-Mms2, we conclude that the importance of this residue stems primarily from its structural role in stabilizing an active site loop.",
