FIGURE 5: Comparison of HutA1 and HutA2 properties by bioinformatics. (A) Model of the genomic region surrounding hutA1 and hutA2 sequence. (B) Bars show the alignment of the N-terminal domain containing the TonB box and the plug domain between HutA1, HutA2 and FpvA (PDB: 2IAH). Numbers indicate the amino acid position of the full-length sequence. (C) Structural model of HutA1 and HutA2 created by structural modeling as described in Materials and Methods.
