The X-ray crystal structure of native hydroxynitrile lyase from Hevea brasiliensis (Hb-HNL) has been determined at 1.1 A resolution. It refined to a final R of 11.5% for all data and an Rfree of 14.4%. The favorable data-to-parameter ratio at atomic resolution made the refinement of individual anisotropic displacement parameters possible. The data also allowed a clear distinction of the alternate orientations of all histidine and the majority of asparagine and glutamine side chains. A number of hydrogen atoms, including one on the imidazole of the mechanistically important His-235, became visible as peaks in a difference electron density map. The structure revealed a discretely disordered sidechain of Ser-80, which is part of the putative catalytic triad. Analysis of the anisotropy indicated an increased mobility of residues near the entrance to the active site and within the active site. | The X-ray crystal structure of native hydroxynitrile lyase from Hevea brasiliensis (Hb-HNL) has been determined at 1.1 A resolution.
