    Protein Summary

    This is PaaK, a critical part of the phenylacetyl-CoA catabolon. The structure 1 (soaked with AMP+COA) is interesting in the following aspects:

    1. Zinc binding site

    2. two different conformations with large domain movements (A/C, and B/D) in crystal lattice, tertrameric, allosteric?

    3. 3 different ligand  state: A: ADP+CoA, C: CoA; B and D: ADP

     

    From PFAM perspective:

    This is a member of our AMP-binding enzyme family, which is part of clan CL0378. Residue 330 is predicted to be catalytic. There are already many structures already known for this family, so not too exciting for us.
