1: inosose [Substance Name] structure Date introduced: January 1, 1973 2: 2-deoxy-scyllo-inosose synthase [Substance Name] responsible for the formation of 2-deoxy-scyllo-inosose from D-glucose; exhibits close similarity to dehydroquinate synthase; not clear whether it catalyzes only the oxidoreduction of C-4 and/or the intramolecular cyclization between C-1 and C-6 Date introduced: March 2, 1994 3: L-glutamine 2-deoxy-scyllo-inosose aminotransferase [Substance Name] Date introduced: February 19, 2003 4: 2-deoxyinosose [Substance Name] structure given in first source; an early intermediate in the biosynthesis of 2-deoxystreptamine Date introduced: August 9, 1992 5: glutamine-scyllo-inosose aminotransferase [Substance Name] Date introduced: January 1, 1974
