Abstract excerpt

Position 106 in CheY is highly conserved as an aromatic residue in the response regulator superfamily. In the structure of the wild-type, apo-CheY, Tyr106 is a rotamer whose electron density is observed in both the inside and the outside positions. In the structure of the T87I mutant of CheY, the...
