A polypeptide includes, in the amino acid sequence of SEQ ID NO: 1 or a similar sequence, at least one specific amino acid substitution on at least one of the 14th, 37th, 209th, 293rd, and 319th amino acid residues from the N-terminal of the amino acid sequence of SEQ ID NO: 1. A polynucleotide, an expression cassette, a vector, and a transformant include a base sequence encoding the amino acid sequence of the polypeptide. A method of producing the polypeptide and a method of producing 2-deoxy-scyllo-inosose are also provided.

Mutant type 2-deoxy-scyllo-inosose synthase

The present invention provides: a lactic acid-producingcomprising at least one gene of a sucrose non-PTS gene group, including at least a sucrose hydrolase gene, provided that a combination of a repressor protein (cscR), a sucrose hydrolase (cscA), a fructokinase (cscK) and a sucrose permease (cscB) and a combination of a sucrose hydrolase (cscA), a fructokinase (cscK) and a sucrose permease (cscB) are excluded, wherein the lactic acid-producingcomprises a lactic acid production enhancing system provided by genetic recombination; and a lactic acid production method including producing lactic acid from a plant-derived sucrose-containing raw material by using the lactic acid-producing

Method for producing lactic acid from plant-derived raw material, and lactic-acid-producing bacterium

The present invention provides: a lactic acid-producingincluding an enzymatic activity of at least one NAD-dependent lactate dehydrogenase and an enzymatic activity of at least one NAD-independent lactate oxidoreductase, both of which are enhanced so as to decompose one of D-lactic acid or L-lactic acid and to produce the other one of D-lactic acid or L-lactic acid; and a lactic acid production method using the lactic acid-producing
