Protein Info for Psest_0085 in Pseudomonas stutzeri RCH2
Updated annotation (from data): alpha-ketoglutarate TRAP transporter, solute receptor component
Rationale: specific phenotype on a-ketoglutarate and no other transporter for this substrate is apparent in the fitness data. (Mutants in another TRAP system, Psest_4268:Psest_4270, have a much milder defect in a-ketoglutarate utilization).
Original annotation: TRAP transporter solute receptor, TAXI family
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.
