Figure 5
Gene clusters of NiFe-hydrogenase encoded by TAG-1, SV-108 and other Zetaproteobacteria isolates and SAGs. Genes are shown in different colors according to COG functional category as listed in a box. Genes annotated as subunits of H2-uptake NiFe-hydrogenase are labeled with bold letters (L: large subunit, S: small subunit, and Cyt B: cytochrome b subunit). Dash lines indicate end of the contig.
