Outline of Final Research Achievements |
X-ray structures of L-ribose isomerase from Acinetobacter sp. and Cellulomonas parahominis were determined. On the basis of the wild-type and mutant form structures in complexes with rare sugars, catalytic reaction mechanism of L-RI including ring-opening mechanism of sugar was proposed. Furthermore, mutant structure analysis supported the essentiality of tetramer formation of L-RI for its enzymatic activity.
