Protein Info for AO353_26685 in Pseudomonas fluorescens FW300-N2E3
Updated annotation (from data): cobalt efflux pump
Rationale: Strong phenotypes on citrate (as a carbon source) but also on cobalt stress. The citrate phenotype may be due to iron deprivation (via chelation by the citrate) leading to heavy metal stress. The cobalt phenotype is more conserved. It is possible that nickel is also a substrate of this efflux pump, as a slight defect in nickel stress was observed, and this protein is 49% identical to the cobalt and nickel exporter dmeF (Atu0891) of Agrobacterium tumefaciens (PMID:27235438). AO353_26685 is annotated as performing zinc or cadium efflux as well (czcD), but unfortunately, we do not have data for those heavy metal stresses. However a role in zinc stress seems doubtful, as a close homolog in strain GW456-L13 is not important for resisting zinc.
Original annotation: cation transporter
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.
