Protein Info for Psest_2055 in Pseudomonas stutzeri RCH2

Updated annotation (from data): cytochrome c550
Rationale: Specific phenotype: utilization of Ethanol. This is the electron acceptor for quinoprotein ethanol dehydrogenase, see PMID:10075429
Original annotation: Cytochrome c, mono- and diheme variants

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.
