Protein Info for Echvi_0120 in Echinicola vietnamensis KMM 6221, DSM 17526
Updated annotation (from data): 2-keto-3-deoxy-D-arabino-heptulosonate-7-phosphate synthase / chorismate mutase (EC 2.5.1.54; EC 5.4.99.5)
Rationale: Important for fitness in most defined media. The N-terminal DHAP region is only 33% identical to the Pyrococcus enzyme (Q8U0A9) but the active site and substrate-binding residues are conserved. The C-terminal chorismate mutase region is diverged but hits PF01817 and no other chorismate mutase was found in the genome.
Original annotation: 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthase
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.
