analysis of the location of hydrogen atoms by time-of-flight neutron Laue technique. The neutron structure of crystalline XI with bound product, D-xylulose, shows, that O5 of D-xylulose is not protonated but is hydrogen-bonded to doubly protonated His54. Also, Lys289, which is neutral in native XI, is protonated, while the catalytic water in native XI has become activated to a hydroxyl anion which is in the proximity of C1 and C2, the molecular site of isomerization of xylose | Streptomyces rubiginosus |
