species 1	species 2			synteny blocks
B. subtilisa Taxonomy	Species name	Taxonomy	Proteome size	average size	longest size
Bacillaceae	Oceanobacillus iheyensis	Bacillaceae	3500	3.6	23
Firmicutes	Shewanella oneidensis	Proteobacteria	4471	2.4	8
Firmicutes	Synechocystis species	Cyanobacteria	3167	2.8	8
Firmicutes	Mycobacterium tuberculosis	Actinobacteria	4187	2.5	11
Bacteria	Methanosarcina acetivorans	Archaea	4540	2.3	7

The average size (number of genes) of synteny blocks is dependent on the taxonomic distance separating a pair of genomes that have been compared at the level of their genetic context.

^a The size of the B. subtilis proteome is 4112.
