At pH 5.0, crystals belong to the hexagonal space group P6?22 and the asymmetric unit is formed by one chain of the protomer of the c-Src-SH3 domain in an open conformation. At pH 7.0, crystals belong to the orthorhombic space group P2?2?2?, with two molecules at the asymmetric unit showing the characteristic fold of the SH3 domain. The residue at position 128 is connected to Glu106 at the diverging Beta-turn through a cluster of water molecules."}
