The findpatterns program (Wisconsin Package Version 9.1, Genetics Computer Group, Madison, WI) was used to search the entire E. coli genome in the SwissProt database (sw:*_ecoli) for the consensus sequence patterns denoted Regions I [(V,L)(X){0,2}(S,A,T)(X){0,2}R(X){0,6}G(K,R)] and II [(S,T)(X){0,4}(V,L)(X){0,2}(N,Q,E)(X){0,2}G(X){0,1}(N,K) (X){0,1}S] in Fig. 3. The sequences in the table contain at least one copy of both sequence patterns.
