Protein Info for HSERO_RS09565 in Herbaspirillum seropedicae SmR1
Updated annotation (from data): nitrite efflux transporter, HPP family
Rationale: Specifically important in stress Sodium nitrite. Related to Synpcc7942_1745, which can be a nitrite uptake transporter (PMID:24904028), but this appears to be exporting nitrite. Besides the HPP domain, it encodes two cytoplasmic CBS domains, which might have a regulatory role.
Original annotation: membrane protein
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.
