Specific CheA-short (CheA(S)) residues, L123 and L126, were identified as critical for CheZ binding. In the CheA(S) 'P1-CheZ nuclear magnetic resonance structure, these residues form an interaction surface on alpha-helix E in the 'P1 domain. Both L123 and L126 are buried in CheA-long (CheA(L)), providing an explanation for why CheA(L) fails to bind CheZ.
