Protein Info for AO353_08595 in Pseudomonas fluorescens FW300-N2E3
Updated annotation (from data): Gamma-glutamyl-putrescine synthetase (EC 6.3.1.11)
Rationale: Specifically important for: Potassium acetate; L-Arginine; Putrescine Dihydrochloride; L-Citrulline. This is the first step in putrescine degradation and is important for the usage of putrescine as either C or N source. The phenotypes on citrulline and arginine might indicate a side pathway where they are converted to putrescine via ornithine decarboxylase (SEED_correct)
Original annotation: gamma-glutamylputrescine synthetase
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.
