CC -!- FUNCTION: Catalyzes the reversible isomerization-deamination of
CC glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P)
CC and ammonium ion. {ECO:0000255|HAMAP-Rule:MF_01241}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-glucosamine 6-phosphate + H2O = beta-D-fructose 6-
CC phosphate + NH4(+); Xref=Rhea:RHEA:12172, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:28938, ChEBI:CHEBI:57634, ChEBI:CHEBI:75989; EC=3.5.99.6;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01241};
CC -!- PATHWAY: Amino-sugar metabolism; N-acetylneuraminate degradation; D-
CC fructose 6-phosphate from N-acetylneuraminate: step 5/5.
CC {ECO:0000255|HAMAP-Rule:MF_01241}.
CC -!- SIMILARITY: Belongs to the glucosamine/galactosamine-6-phosphate
CC isomerase family. NagB subfamily. {ECO:0000255|HAMAP-Rule:MF_01241}.
