Protein Info for Psest_1928 in Pseudomonas stutzeri RCH2

Updated annotation (from data): Nitrite reductase (NAD(P)H) (EC 1.7.1.4)
Rationale: Specifically important for utilizing Sodium nitrate. Automated validation from mutant phenotype: the predicted function (1.7.1.4) was linked to the condition via a SEED subsystem. This annotation was also checked manually.
Original annotation: nitrite reductase [NAD(P)H], large subunit

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.
