The crystal structures of Passiflora edulis hydroxynitrile lyase and its C-terminal peptide depleted derivative are determined by molecular replacement method using the template structure of a heat stable protein, SP1, from Populus tremula at 2.8 and 1.8 A resolution, respectively. Passiflora edulis hydroxynitrile lyase belongs to dimeric alpha+beta barrel superfamily consisting of a central beta-barrel in the middle of a dimer. The structure of Passiflora edulis hydroxynitrile lyase complexed with (R)-mandelonitrile is also determined. The hydroxyl group of (R)-mandelonitrile forms hydrogen bonds with His8 and Tyr30 in the active site, whereas the nitrile group is oriented toward the carboxyl group of Glu54, unlike other hydroxynitrile lyases, where it interacts with basic residues typically 747750

The crystals belong to the monoclinic space group P2(1) with unit cell parameters a = 69.9, b = 95.1, c = 95.6 A, and beta = 118.5 degrees.

Display the word mapDisplay the reaction diagram Show all sequences 4.1.2.10structure at a crystallographic resolution of 2.5 A and comparison with the S-selective HNL from Hevea brasiliensis. The structures exhibit an alpha/beta-hydrolase fold and a Ser-His-Asp catalytic triad. Modeling of complexes of the enzymes with both (R)- and (S)-mandelonitrile leads to a catalytic mechanism, in which His236 from the catalytic triad acts as a general base and the emerging negative charge on the cyano group is stabilized by main-chain amide groups and an alpha-helix dipole very similar to alpha/beta-hydrolases 727309
