Figure 1

Alignment of amino acid sequences of PsGrx with the sequences of other Grxs. The displayed sequences are Pseudoalteromonas haloplanktis Grx (YP_338909), Pseudoalteromonas agarivorans Grx (WP_004588615), Pseudoalteromonas haloplanktis Grx (WP_016708488), Pseudoalteromonas undina Grx (WP_010391834), and Rheinheimera nanhaiensis Grx (WP_008217797). The shaded boxes in same color indicate identical residues. Symbols: closed triangles, cysteines (C) in the active site; pentagrams, residues involved in glutathione-binding site.
