Protein Info for BPHYT_RS02740 in Burkholderia phytofirmans PsJN
Updated annotation (from data): N-acetylglucosamine-specific PTS system, I, HPr, and IIA components (nagF)
Rationale: Specifically important on NAG and cofit with the IIBC component nearby (BPHYT_RS02745). 58% identical to nagF or H16_A0311 of R. eutropha, which is important for NAG utilization (PMCid:PMC3127587). 58% similar to PA3760, which is required for NAG utilization in P. aeruginosa (PMCid:PMC2542419)
Original annotation: PTS glucose transporter subunit IIA
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.
