Protein Info for Pf1N1B4_412 in Pseudomonas fluorescens FW300-N1B4
Updated annotation (from data): L-arabinose 1-dehydrogenase / D-galactose 1-dehydrogenase (EC 1.1.1.46; EC 1.1.1.48)
Rationale: Both of these sugars are catabolized via a 1-dehydrogenase followed by lactonase and dehydratase reactions. This is the only dehydrogenase is specifically important for either of these carbon sources in several Pseudomonas, apart from a alpha-ketoglutarate semialdehyde dehydrogenase that is expected to be the last dedicated step in L-arabinose catabolism (i.e., Pf6N2E2_612). L-arabinose and D-galactose are chemically similar and some dehydrogenases are already known to act on both substrates.
Original annotation: 3-oxoacyl-[acyl-carrier protein] reductase (EC 1.1.1.100)
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.
