Figure 9: Domains within hypothetical DsrB protein from a gutless worm�s symbiont. All the 313 amino residues of the sequence GUTLS_WRM_ELBA_ READ_1433974420 are presented. The sulfite reductase ferredoxin-like half domain, position 1 � 67, is blue. The sulfite reductase 4Fe-4S domain, 74 � 293, is green. The 4Fe-4S binding site, 165 � 174, and 4Fe-4S binding site, 184 � 207, are yellow insertions. The repressor of phase-1 flagellin, 270 � 277, is red. Predicted protein structures were retrieved from the following servers: ESyPred3D, position 11 � 149 (bold cursive), 3D-JIGSAW, 153 � 206 (bold) and GENO3D, 207 � 299 (cursive).
