    Protein Summary

    ShpA is a  histidine phosphotransfer protein. It is a component of a multiple stage two-component  signal transduction  system which relay phosphoryl group from His-Asp-His-Asp. The pathway is involved in regulating stalk biogenesis in Caulobacter crescentus.

    The active site is at His56. The structure is similar to yeast HPt YPD1 and a few recently solved HPt proteins.
