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}.
