    Protein Summary

    The Sbal_3149 gene from Shewanella baltica os155 encodes the YP_001051499, a member of the DUF416 group (PF04222, COG3068). The genome context analysis of Sbal_3149 suggests a high probability (score 0.87) of a functional association with histidine kinases (Sbal_3148 gene, a multisensor hybrid histidine kinase), indicating a role in signaling.

    2q9r structure shows strong similarity with another homolog structure determined by the PSI (PDB id: 3F7C, DALI Z-score 20.2 with rmsd 2.2 Å over 168 residues, sequence identity 23%).



    To do: look more systematically at genome context, search for other functional indicators (e.g. expression array).

    See 3f7c  entry.
