Protein Info for Pf1N1B4_772 in Pseudomonas fluorescens FW300-N1B4
Updated annotation (from data): ABC transporter for L-asparagine and L-glutamate, permease component 1
Rationale: Specifically important in carbon source L-Asparagine. Also important for glutamate utilization. We do not have fitness data for aspartate utilization - it may well transport aspartate as well. Also note that the aspariganase (Pf1N1B4_2023) is predicted to be cytoplasmic and is important for asparagine utilization, so we do not think that asparagine is converted to aspartate before uptake.
Original annotation: Glutamate Aspartate transport system permease protein GltJ (TC 3.A.1.3.4)
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.
