Identification of conserved Pfam domains in the PsrA family of proteins. ClustalW multiple alignment of PsrA family proteins containing conserved Pfam domains. (A) Multiple alignment of Pfam domain PF04879 (4Fe-4S binding domain) with S. oneidensis MR-1 PsrA (PsrA_MR1), S. Typhimurium LT2 PhsA (PhsA_LT2), and W. succinogenes PsrA (PsrA_Ws). (B) Multiple alignments of Pfam domain PF01568 (bis-MGD binding domain) with PsrA and PhsA proteins. Identical residues are shaded.
