Dear Shane,
To add a bit of detail to Frank von Delft's suggestion,
perhaps the best example is the structure of the yeast F1-ATPase that has 3
copies in the asu, from David Mueller's lab in Chicago. Two of these are very
similar, but the third is rather different and shows a (physiologically
relevant) phosphate binding site that is not found in the other two copies. I
would not describe the differences as dramatic though.
The paper is: Kabaleeswaran et al., EMBO J 25, 5433 (2006)
PDB ID 2HLD
Best wishes,
Andrew Leslie
