Characterization of a restriction modification system from the commensal Escherichia coli strain A0 34/86 (O83:K24:H31)

Table 1 Sequence comparisons of HsdR and HsdM subunits

The R-M systems CfrAI, EcoAI and EcoEI are prototypes of Type IB family, StySKI identifies the first member of the IB family in Salmonella species [38], EcoKI is a prototype member of Type IA [39]. The values are the per cent identity of aligned sequences. EcoA0ORF42P is from E. coli A0 34/86 (O83: K24: H31), EcoO157ORF5947P is from E. coli O157:H7, EcoKO157ORF5307P is from E. coli O157:H7 Sakai strain [40] and EcoCFTORF5424P is from E. coli CFTO73. P means putative R-M system, NA – the sequence is not available, ¹ alignment of the number of aa so far available
