Protein Info for BPHYT_RS02745 in Burkholderia phytofirmans PsJN
Updated annotation (from data): N-acetylglucosamine-specific PTS system, IIBC components (nagE)
Rationale: Specifically important on NAG and cofit with the I-HPr-IIA component nearby (BPHYT_RS02740). CDD or PFam do not show any sign of this gene containing a IIA component, so the SEED annotation is misleading. 62% similar to H16_A0312 (nagE) and 58% similar to PA3761, which are both involved in NAG utilization (PMCid:PMC3127587, PMCid:PMC2542419). KEGG_correct.
Original annotation: PTS system N-acetylglucosamine-specific transporter subunit IIBC
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.
