CRYSTAL STRUCTURE OF THE NASTURTIUM SEEDLING XYLOGLUCANASE ISOFORM NXG1
Overview
High-resolution, three-dimensional structures of the archetypal glycoside, hydrolase family 16 (GH16) endo-xyloglucanases Tm-NXG1 and Tm-NXG2 from, nasturtium (Tropaeolum majus) have been solved by x-ray crystallography., Key structural features that modulate the relative rates of substrate, hydrolysis to transglycosylation in the GH16 xyloglucan-active enzymes, were identified by structure-function studies of the recombinantly, expressed enzymes in comparison with data for the strict xyloglucan, endo-transglycosylase Ptt-XET16-34 from hybrid aspen (Populus tremula x, Populus tremuloides). Production of the loop deletion variant, Tm-NXG1-DeltaYNIIG yielded an enzyme that was structurally similar to, Ptt-XET16-34 and had a greatly increased transglycosylation:hydrolysis, ratio. ...
