Figure 6.

World map illustrating the global spread of IMP enzymes. The map was prepared as described for Figure 4 except that IMP-specific search strings were used to retrieve articles and that countries with IMP occurence were colored in green, symbolizing MBLs. In some cases, where no published articles were available, GenBank entries were taken into account, e.g., for Thailand. For more details see Supporting Information S3-S5.
