    Protein Summary

    Pfam Summary: The first match to this protein on building was in family Glucosamine_iso PF01182. This family has many other structures.

     

     

    The structure of  target id 402861 was determined by three-wavelengh Se-MAD at a resolution of 1.91 Angstroms. A fastSCOP search on the structure suggests that this target shows a NagB/RpiA/CoA-Transferase-like SCOP fold. Shown below is a ribbons representation of the structure of the monomer color-coded with the N-terminal end in blue and the C-terminal end in red. The structure is similar to 6-phosphoglucolactonase (EC 3.1.1.31) suggesting that this function is performed by this target. This enzyme performs the hydrolysis of 6-phosphoglucolactone to 6-phosphpgluconate, the second step of the pentose phosphate shunt.

     The crystal structure suggests that a dimer is likely to be a significant oligomerization form in solution. Shown below is a ribbons representation of the dimer with the individual chains in blue and yellow.
