Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Converts N-acetylmannosamine-6-phosphate (ManNAc-6-P) to N-acetylglucosamine-6-phosphate (GlcNAc-6-P).Curated

Catalytic activityi

N-acyl-D-glucosamine 6-phosphate = N-acyl-D-mannosamine 6-phosphate.

Pathwayi: N-acetylneuraminate degradation

This protein is involved in step 3 of the subpathway that synthesizes D-fructose 6-phosphate from N-acetylneuraminate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. N-acetylneuraminate lyase (nanA)
  2. N-acetylmannosamine kinase (nanK)
  3. Putative N-acetylmannosamine-6-phosphate 2-epimerase (nanE)
  4. N-acetylglucosamine-6-phosphate deacetylase (nagA)
  5. Glucosamine-6-phosphate deaminase (nagB)
This subpathway is part of the pathway N-acetylneuraminate degradation, which is itself part of Amino-sugar metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-fructose 6-phosphate from N-acetylneuraminate, the pathway N-acetylneuraminate degradation and in Amino-sugar metabolism.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
