Protein Info for BT1758 in Bacteroides thetaiotaomicron VPI-5482
Updated annotation (from data): fructose transporter
Rationale: Specifically important for utilizing fructose. Also important for utilizing fructooligosaccharides. Part of a PUL for utilizing levan (PMC3225772).
Original annotation: glucose/galactose transporter (NCBI ptt file)
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.
