Protein Info for AO353_03400 in Pseudomonas fluorescens FW300-N2E3
Updated annotation (from data): D-mannose isomerase (EC 5.3.1.7)
Rationale: Specifically important for: D-Mannose. Often annotated as N-acylglucosamine 2-epimerase, but this is also distantly related to the D-mannose isomerase Sama_0560. The putative fructokinase AO353_25910 is also important for mannose utilization, which would complete the pathway.
Original annotation: sugar isomerase
These analyses and tools can help you predict a protein's function, but be skeptical. For enzymes, over 10% of annotations from KEGG or SEED are probably incorrect. For other types of proteins, the error rates may be much higher. MetaCyc and Swiss-Prot have low error rates, but the best hits in these databases are often quite distant, so this protein's function may not be the same. TIGRFam has low error rates. Finally, many experimentally-characterized proteins are not in any of these databases. To find relevant papers, use PaperBLAST.
