BACKGROUND: Aldose reductase (AR) is an NADPH-dependent enzyme implicated in long-term diabetic complications. Buried at the bottom of a deep hydrophobic cleft, the NADPH coenzyme is surrounded by the conserved hydrophilic residues of the AR active site. The existence of an anionic binding site near the NADP+ has been determined from the structures of the complexes of AR with citrate, cacodylate and glucose-6-phosphate. The inhibitor zopolrestat binds to this anionic site, and in the hydrophobic cleft, after a change of conformation which opens a 'specificity' pocket. RESULTS: The crystal structures of the porcine AR holoenzyme and its complexes with the inhibitors tolrestat and sorbinil have been solved; these structures are important as tolrestat and sorbinil are, pharmaceutically, the most well-studied AR inhibitors. The active site of the holoenzyme was analyzed, and binding of the inhibitors was found to involve two contact zones in the active site: first, a recognition region for hydrogen-bond acceptors near the coenzyme, with three centers, including the anionic site; and second, a hydrophobic contact zone in the active-site cleft, which in the case of tolrestat includes the specificity pocket. The conformational change leading to the opening of the specificity pocket upon tolrestat binding is different to the one seen upon zopolrestat binding; this pocket binds inhibitors that are more effective against AR than against aldehyde reductase. CONCLUSIONS: The active site of AR adapts itself to bind tightly to different inhibitors; this happens both upon binding to the inhibitor's hydrophilic heads, and at the hydrophobic and specificity pockets of AR, which can change their shape through different conformational changes of the same residues. This flexibility could explain the large variety of possible substrates of AR.

Figure 1. Overall views of the holoenzyme form of pig lens AR. (a) Schematic drawing obtained using the program SETOR [37], showing the TIM barrel structure (green), the sorbinil molecule (brown ball-and-stick) and the NADP+ (dark blue ball-and-stick) lying between strands S7 and S8, with loop L7 in light blue bent over it. (b) View of the surface of the molecule generated using the program GRASP [38], with the sorbinil molecule (ball-and-stick) bound in the active-site cleft. The colors correspond to electrostatic potential surfaces (positive in blue; negative in red) calculated using charge distributions on all protein residues using the program XPLOR [32], and on NADP+, from Pavelites et al. [39]. Note the positively charged bottom of the pocket, below the sorbinil molecule.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
