additional information TAD possesses the catalytic triad Ser136, Tyr149, and Lys153. No activity with L-xylose, D-ribose and 2-deoxy-D-ribose. TAD does not oxidize ketoses (D-fructose and D-sorbose), sugar alcohols (D-sorbitol, galactitol, inositol, L-arabitol and xylitol), uronic acids (D-galacturonic acid and D-glucuronic acid), aldonic acids (L-gulonic acid and 2-keto-L-gulonic acid), aromatic alcohols (benzyl alcohol and catechol), aliphatic alcohols (1-nonanol, 1-decanol, 3-hydroxybutyric acid and 2,3-butanediol), and hydroxysteroids (androsterone, testosterone, 20alpha/beta-hydroxyprogesterone, cholic acid, cortisol and corticosterone). No significant activity ketones (4-nitroacetophenone, camphorquinone, 2,3-hexanedione and diacetyl) and aldehydes (4-nitrobenzaldehyde, pyridine-3-aldehyde, 1-nonanal and citral) Thermus thermophilus HB8 ?
