Gene order in Hydrogenase gene cluster II of SP-41 compared to homologous regions in other Proteobacteria. Comparison of the gene order in the hydrogenase gene cluster II of SP-41 with homologous regions in Hydrogenovibrio thermophilus MA2-6, Hydrogenovibrio marinus MH-110 T, Cupriavidus necator H16 and Ghiorsea bivora TAG-1 T. Color background rectangles are used to highlight gene syntheny. For MA2-6 and TAG-1 the reverse-complementary strand to the reference sequence is visualized, in order to maximize the number of homologs aligned to the other genomes. For MH-110, the region is different in the two available genome sequences: a gene duplication is present in the assembly by Scott et al.  but not in that by Jo et al.
