Protein Info for PS417_27130 in Pseudomonas simiae WCS417
Updated annotation (from data): Gamma-aminobutyrate:alpha-ketoglutarate aminotransferase (EC 2.6.1.19)
Rationale: Specifically important for: Putrescine Dihydrochloride. KEGG annotates this as putrescine aminotransferase, probably based on similarity to spuC (PA0299) of P. aeruginosa, but it is believed that only the g-glutamyl- pathway operates in P. aeruginosa (X. Yao et al 2011, PMC3147493)
Original annotation: aminotransferase
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.
