Figure 2

Genomic organization of the genes coding for flagellum components in complete archaeal genomes (fla clusters). Numbers within brackets correspond to the locus tags of each gene. A // sign indicates that the following components are elsewhere in the genome. The genes annotated as hyp 1 and hyp 2 are probable distant homologues of flaD/E. Genes colored in grey are homologues of chemotaxis components, as discussed in the text. Remaining genes where no name is indicated are annotated as hypothetical. A Genomic organization of type I clusters (fla 1). These are found only in Euryarchaea and are characterized by the presence of flaC and flaD/E and by a conserved gene order flaA/B, flaC, flaD, flaF, flaG, flaH, flaI, flaJ. B Genomic organization of the type II clusters (fla 2). These are found in Crenarchaea and in some Euryarchaea and are characterized by the absence of flaC and flaD/E and by a conserved gene order flaA/B, flaC, flaD, flaG, flaF, flaH, flaI, flaJ.
