CC   -!- FUNCTION: Catalyzes the first step in hexosamine metabolism,
CC       converting fructose-6P into glucosamine-6P using glutamine as a
CC       nitrogen source (By similarity).
CC   -!- CATALYTIC ACTIVITY: L-glutamine + D-fructose 6-phosphate = L-
CC       glutamate + D-glucosamine 6-phosphate.
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Contains 1 glutamine amidotransferase type-2 domain.
