| + | == Publication Abstract from PubMed == | ||
| + | In sequenced genomes, protein coding regions with unassigned function constitute between 10 and 50% of all open reading frames. Often key enzymes cannot be identified using sequence homology searches. For example, despite the fact that methanogens have an apparently functional gluconeogenesis pathway, standard tools have been unable to identify a fructose-1,6-bisphosphatase (FBPase) gene in the sequenced Methanoccocus jannaschii genome. Using a combination of functional and structural tools, we have shown that the protein product of the M. jannaschii gene MJ0109, which had been tentatively annotated as an inositol monophosphatase (IMPase), has both IMPase and FBPase activities. Moreover, several gene products annotated as IMPases from different thermophilic organisms also possess FBPase activity. Thus, we have found the FBPase that was 'missing' in thermophiles and shown that it also functions as an IMPase. | ||
