Protein Info for Sama_2211 in Shewanella amazonensis SB2B
Updated annotation (from data): alpha-ketoglutarate TRAP transporter, large permease component
Rationale: specific phenotype on a-ketoglutarate. A putrescine ABC transporter (Sama_2642:Sama_2638) is also important in this condition, which is not explained. This organism can also utilize succinate or fumarate (but not L-malate), which we do not have fitness data for these under aerobic conditions. This could also transport some C4 compounds.
Original annotation: C4-dicarboxylate transport protein (RefSeq)
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.
