RT "Complete sequence of Bacillus selenitireducens MLS10.";
RL Submitted (OCT-2009) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the reversible isomerization-deamination of
CC glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate
CC (Fru6P) and ammonium ion. {ECO:0000256|HAMAP-Rule:MF_01241}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-glucosamine 6-phosphate + H2O = beta-D-fructose
CC 6-phosphate + NH4(+); Xref=Rhea:RHEA:12172, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:28938, ChEBI:CHEBI:57634, ChEBI:CHEBI:75989;
CC EC=3.5.99.6; Evidence={ECO:0000256|HAMAP-Rule:MF_01241,
CC ECO:0000256|SAAS:SAAS01119605};
CC -!- PATHWAY: Amino-sugar metabolism; N-acetylneuraminate degradation;
CC D-fructose 6-phosphate from N-acetylneuraminate: step 5/5.
CC {ECO:0000256|HAMAP-Rule:MF_01241}.
CC -!- SIMILARITY: Belongs to the glucosamine/galactosamine-6-phosphate
CC isomerase family. NagB subfamily. {ECO:0000256|HAMAP-
CC Rule:MF_01241}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation
CC of feature annotation. {ECO:0000256|HAMAP-Rule:MF_01241}.
