The authors would like to make the following corrections to their article. In two places the Protein Data Bank IDs were incorrect. At the end of the first paragraph of the ‘Crystallization and structure determination’ section in the ‘Materials and Methods’ the PDB IDs should be 3H0F, 3H0H, and 3H0I. In the ‘Fynr96w mutation alters the SH3 RT loop hydrogen-bond network’ section the PDB IDs should be 3H0F, 3H0H, 3H0I, 6IPY, and 6IPZ. Also, the Fynr96w in the title ‘Fynr96w mutation alters the SH3 RT loop hydrogen-bond network’ should be FynR96W. The authors apologize for any confusion caused by these errors.
