A method for producing psicose, comprising converting psicose-6-phosphate into psicose by bringing psicose-6-phosphate into contact with a psicose-6-phosphate phosphatase, a microorganism expressing the same, or a culture of the microorganism, wherein the psicose-6-phosphate phosphatase is derived from any one selected from the group consisting of the genus Alicyclobacillus, Amycolatopsis, Anaerolinea, Archaeoglobus, Bacillus, Caldicellulosiruptor, Caldilinea, Caldithrix, Carboxydocella, Carboxydothermus, Chloroflexi, Defluviitoga, Deinococcus, Desulfurococcus, Dictyoglomus, Effusibacillus, Fervidobacterium, Geobacillus, Halococcus, Hydrogenivirga, Hydrogenobacter, Hyperthermus, Kosmotoga, Marinitoga, Meiothermus, Mesotoga, Metallosphaera, Methanocella, Methanococcoides, Methanohalobium, Methanolobus, Methanosarcina, Methanothermus, Petrotoga, Picrophilus, Pseudonocardia, Pyrococcus, Pyrodictium, Rhodothermus, Slackia, Staphylothermus, Sulfolobus, Thermanaerothrix, Thermoanaerobacter, Thermoanaerobacterium, Thermobifida, Thermococcus, Thermocrinis, Thermoflexus, Thermotoga, Thermus, and Truepera.
A method for producing psicose, comprising bringing starch, maltodextrin, sucrose, or a combination thereof into contact with (a) a psicose-6-phosphate phosphatase;
- fructose-6-phosphate-3-epimerase;
- glucose-6-phosphate-isomerase;
- phosphoglucomutase or glucokinase;
- and α-glucan phosphorylase, starch phosphorylase, maltodextrin phosphorylase, sucrose phosphorylase, α-amylase, pullulanase, isoamylase, glucoamylase, α-glucanotransferase, polyphosphate glucokinase, or sucrase;
- or (b) a microorganism expressing the enzymes of item (a) or a culture of the microorganism,
- wherein the psicose-6-phosphate phosphatase is derived from any one selected from the group consisting of the genus Alicyclobacillus, Amycolatopsis, Anaerolinea, Archaeoglobus, Bacillus, Caldicellulosiruptor, Caldilinea, Caldithrix, Carboxydocella, Carboxydothermus, Chloroflexi, Defluviitoga, Deinococcus, Desulfurococcus, Dictyoglomus, Effusibacillus, Fervidobacterium, Geobacillus, Halococcus, Hydrogenivirga, Hydrogenobacter, Hyperthermus, Kosmotoga, Marinitoga, Meiothermus, Mesotoga, Metallosphaera, Methanocella, Methanococcoides, Methanohalobium, Methanolobus, Methanosarcina, Methanothermus, Petrotoga, Picrophilus, Pseudonocardia, Pyrococcus, Pyrodictium, Rhodothermus, Slackia, Staphylothermus, Sulfolobus, Thermanaerothrix, Thermoanaerobacter, Thermoanaerobacterium, Thermobifida, Thermococcus, Thermocrinis, Thermoflexus, Thermotoga, Thermus, and Trueper.
