Multiple protein sequence of the variable regions in the hsdS genes. Both copies of the hsdS gene had a repetitive region of varying length consisting of TELS and AELS units (highlighted in orange and yellow, respectively). Note that in both copies, the length and composition of the repeat does not correspond to strain subtype. Strain names are to the right and highlighted in blue for type 1 and green for type 2. a Repeat region in the MPN089 copy of the hsdS gene. This is part of the variation in the 108000–126000 region shown in Fig. 2c. b Repeat region in the MPN343 copy of the hsdS gene. This is the variation in the 409700–410900 region shown in Fig. 2c
