Fig. 4.

Comparison of the cbb1 gene cluster of Thermodesulfobium spp. with the gene clusters in Ammonifex spp. and T. autotrophica in terms of gene order and amino acid sequence identity of the encoded proteins. Solid vertical lines denote high identity values and dotted lines denote lower identity values. FBPAP, fructose-1,6-bisphosphate aldolase/phosphatase; RubisCO III, ribulose-1,5-bisphosphate carboxylase, form III; TK-C, transketolase, C-terminal section; TK-N, transketolase, N-terminal section. Reg is annotated as a transcriptional regulator, LytTR family.
