Protein Info for CCNA_01356 in Caulobacter crescentus NA1000

Updated annotation (from data): 5-dehydro-2-deoxygluconokinase (EC 2.7.1.92); possible 5-dehydro-2-deoxyphosphogluconate aldolase DUF2090 (EC 4.1.2.29)
Rationale: Important for utilizing m-Inositol. This protein is a fusion of 5-keto-deoxygluconate kinase and DUF2090. As DUF2090 has distant similarity to aldolases, it may provide the missing 5-dehydro-2-deoxyphosphogluconate aldolase activity.
Original annotation: 5-dehydro-2-deoxygluconokinase IolC

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.
