Protein Info for Pf1N1B4_4511 in Pseudomonas fluorescens FW300-N1B4

Updated annotation (from data): D-galacturonate dehydrogenase (EC 1.1.1.203)
Rationale: Important on D-galacturonate; KEGG now has pfo:Pfl01_3452 as uronate dehydrogenase which is correct but less specific (KEGG_correct)
Original annotation: UDP-glucose 4-epimerase (EC 5.1.3.2)

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.
