16818232-5	2006	Flexible side chains and bound water molecules form the majority of the base contacts and potentially could rearrange when the U2AF(65) structure adapts to different Py tract sequences.	Water	31-36	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	127-134	
17188295-3	2007	Previously, the structure of a U2AF(65) variant in complex with poly(U) RNA suggested that rearrangement of flexible side-chains or bound water molecules may contribute to degenerate Py-tract recognition by U2AF(65).
