    Summary:Lipocalin-type Prostaglandin D synthase (L-PGDS) acts as the PGD(2)-synthesizing enzyme in the brain of various mammalian species. It belongs to the lipocalin superfamily and is the first member of this family to be recognized as an enzyme. Although the solution and crystal structure of L-PGDS has been determined to understand the molecular mechanism of catalytic reaction, the structural analysis of L-PGDS in complex with its substrate remains to be performed. Here, we present the nearly complete assignment of the backbone and side chain resonances of L-PGDS/substrate analog (U-46619) complex. This study lays the essential basis for further understanding the substrate recognition mechanism of L-PGDS.

    Summary:Lipocalin-type prostaglandin (PG) D synthase (L-PGDS) is a multi functional protein acting as a PGD2 synthesizing enzyme, a transporter or scavenger of various lipophilic ligands, and an amyloid β chaperon in the brain. L-PGDS is a member of the lipocalin superfamily and has the ability to bind various lipophilic molecules such as prostanoid, retinoid, bile pigment, and amyloid β peptide. However, the molecular mechanism for a wide variety of ligand binding has not been well understood. In this study, we determined by NMR the structure of recombinant mouse L-PGDS and L-PGDS/PGH2 analog complex. L-PGDS has the typical lipocalin fold, consisting of an eight-stranded β-barrel and a long α-helix. The interior of the barrel formed a hydrophobic cavity opening to the upper end of the barrel, the size of which was larger than those of other lipocalins and the cavity contained two pockets. Kinetic studies and molecular docking studies based on the result of NMR titration experiments provide the direct evidence for two binding sites for PGH2 and retinoic acid in the large cavity of L-PGDS. Structural comparison of L-PGDS/U-46619 complex with apo-L-PGDS showed that the H2-helix, CD-loop, and EF-loop located at the upper end of the β-barrel change the conformation to cover the entry of the cavity upon U-46619 binding. These results indicated that the two binding sites in the large cavity and induced fit mechanism were responsible for the broad ligand specificity of L-PGDS.
