CC -!- FUNCTION: Catalyzes the first step in hexosamine metabolism, converting
CC fructose-6P into glucosamine-6P using glutamine as a nitrogen source.
CC {ECO:0000256|HAMAP-Rule:MF_00164}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-fructose 6-phosphate + L-glutamine = D-glucosamine 6-
CC phosphate + L-glutamate; Xref=Rhea:RHEA:13237, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:58359, ChEBI:CHEBI:58725, ChEBI:CHEBI:61527; EC=2.6.1.16;
CC Evidence={ECO:0000256|ARBA:ARBA00001031, ECO:0000256|HAMAP-
CC Rule:MF_00164};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00164}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00164}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
