Crystallization (Commentary)

Crystallization (Comment) Organism
in ternary complex with NADPH and a 5-arylidene-2,4-thiazolidinedione aldose reductase inhibitor, [5-(3-carboxymethoxy-4-methoxybenzylidene)-2,4-dioxothiazolidin-3-yl]acetic acid to 1.99 A resolution. The partially disordered inhibitor forms a tight network of hydrogen bonds with the active site residues Tyr50 and His113 and coenzyme. pi-Stacking interactions with several conserved active site tryptophan residues and hydrogen-bonding interactions with the non-conserved C-terminal residue Pro301 in aldehyde reductase ALR1 contribute to inhibitor selectivity. In particular for the potent inhibitor [5-(3-carboxymethoxy-4-methoxybenzylidene)-2,4-dioxothiazolidin-3-yl]acetic acid, the rotameric state of the conserved residue Trp220 in ALR1, i.e Trp 219 in aldose reductase, is important in forming a pi-stacking interaction with the inhibitor in aldose reductase and contributes to the difference in the binding of the inhibitor to the enzymes Sus scrofa
purified aldehyde reductase, ALR1, in ternary complex with NADPH and [5-(3-carboxymethoxy-4-methoxybenzylidene)-2,4-dioxothiazolidin-3-yl]acetic acid, hanging drop method, 17-18 mg/ml protein in 5 mM Tris-HCl, pH 6.5, containing 5 mM 2-mercaptoethanol, mixed with NADPH and inhibitor in a 1:20:3molar ratio, the reservoir solution contains 2.0 M ammonium sulfate, and 0.1 M Tris-HCl buffer, pH 8.5, 10 days, X-ray diffraction structure determination and analysis at 1.99 A resolution Sus scrofa

[5-(3-carboxymethoxy-4-methoxybenzylidene)-2,4-dioxothiazolidin-3-yl]acetic acid crystallization data. The rotameric state of the conserved residue Trp220 in aldehyde reductase ALR1, i.e Trp 219 in aldose reductase ALR2, is important in forming a pi-stacking interaction with the inhibitor in aldose reductase and contributes to the difference in the binding of the inhibitor to the enzymes; i.e. CMD, a potent inhibitor of ALR2, but not for ALR1. For binding to ALR1, the partially disordered inhibitor forms a tight network of hydrogen bonds with the active site residues Tyr50 and His113 and NADPH, structure molecular modelling, overview. The non-conserved C-terminal residue Leu300 in ALR2, which is Pro301 in ALR1, contributes to inhibitor selectivity Sus scrofa
