CCL: steroid 5-alpha-reductase: a homology model

["Fabrizio Manetti" <manettif++unisi.it>]

 Dear CCLers,
 working on the steroid 5-alpha-reductase enzyme, I recently found a paper
 ("Modeling Steroid 5alpha-reductase and Characterizing Its Potential Active
 Sites", Chinese Journal of Structural Chemistry 2012, 31, 1618-1626) that
 describes a homology model of this protein and reports a PDBID (I523) for its
 structure. Unfortunately, this ID does not correspond to any PDB entry (its
 format is unusual among PDB codes).
 Morevoer, the corresponding author of this paper (LI Jun-Qian, College of
 Chemistry and Chemical Engineering, Fuzhou University, Fuzhou 350002, China) did
 not reply to my email messages requiring a pdb file of the structure.
 Given these unsuccessful attempts, I ask whether anyone has in her/his hands the
 homology model structure built by Li or the structure of the same enzyme
 obtained by means of experimental or theoretical approaches.
 Thank you for your collaboration.
 Regards,
 Fabrizio
