Domain organization of EBPs in Clostridiales. a The domain architecture of EBPs. PAS, Per-Arnt-Sim domain; GAF, cyclic GMP-specific phosphodiesterases, adenylyl cyclases and FhlA; PTS-HPr, PTS system histidine phosphocarrier protein HPr-like; PrpR_N, N-terminal domain of Propionate catabolism activator; ACT, aspartokinase-chorismate mutase-TyrA; CBS, cystathinoine β-synthase domain; Fer4, 4Fe-4S binding domain; Fe_hyd_lg_C, iron only hydrogenase large subunit, C-terminal domain; FeS, Fe-S cluster; V4R, vinyl 4 reductase domain; RR, response regulator domain. b Distribution of TCS and OCS-type EBPs in Enterobacteriales and Clostridiales. c Distribution of PAS-containing EBPs in 23 genera of Clostridiales
