Function
function
Catalyzes the reversible isomerization-deamination of glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P) and ammonium ion.
Catalytic activity
- alpha-D-glucosamine 6-phosphate + H2O = beta-D-fructose 6-phosphate + NH4+
Pathway
Amino-sugar metabolism; N-acetylneuraminate degradation; D-fructose 6-phosphate from N-acetylneuraminate: step 5/5.
