Protein Info for AO353_17230 in Pseudomonas fluorescens FW300-N2E3

Updated annotation (from data): Beta-ketoadipate enol-lactone hydrolase (EC 3.1.1.24)
Rationale: Specifically important for utilizing L-Tryptophan. Automated validation from mutant phenotype: the predicted function (3-OXOADIPATE-ENOL-LACTONASE-RXN) was linked to the condition via a MetaCyc pathway. This annotation was also checked manually.
Original annotation: 3-oxoadipate enol-lactonase

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.
