Protein Info for Pf6N2E2_5112 in Pseudomonas fluorescens FW300-N2E2
Annotation: 4-hydroxy-3-methylbut-2-enyl diphosphate reductase (EC 1.17.1.2)
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.
