Protein Info for Shew_2371 in Shewanella loihica PV-4

Updated annotation (from data): actP-like component of L-lactate and L-malate uptake system
Rationale: annotated as an acetate transporter, but important for L-lactate and L-malate utilization; see Sama_2372 (DUF4212)
Original annotation: Na+/solute symporter (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.
