[117] d-glucosaminic acid dehydrase

1966
Publisher Summary This chapter discusses the determination of D-glucosaminic acid dehydrase. The dehydrase catalyzes the conversion of D-glucosaminic acid to 2-keto-3-deoxy-D-gluconie acid (KDG) and NH 3 . The α-keto acid is measured as its semicarbazone according to the procedure of MacGee and Doudoroff.

The phosphorylation of D-(+)-glucosamine by crystalline yeast hexokinase

Biochimica et Biophysica Acta, 1951
d-glucosamine has been shown to be converted to a phosphorylated amino sugar by ATP in the presence of crystalline yeast hexokinase and magnesium ions. The rate of the reaction is approximately that observed for d-glucose. The turnover number of the enzyme for glucosamine is 12,000 moles/105 grams hexokinase/minute at pH 7.8 and 30°.
