Figure 5.

Intein size distributions in the Haloferax, Haloarcula, and Halorubrum. The size of inteins in the Haloarcula (A), Haloferax (B), and Halorubrum (C) are indicated in the column corresponding to the intein allele. Mini-inteins are colored yellow, large inteins are colored teal, black boxes indicate no intein, and white boxes indicate missing data, clusters from Figure 3 are indicated by numbered orange boxes. The cdc21-a, and b sequences for Halorubrum sp. J07HR59, though smaller than the rest, cannot be considered mini-inteins, as the intein sequences in these positions are not complete.
