Abstract:
A hexuronate C4-epimerase with improved conversion activity and a method for producing D-tagatose using the hexuronate C4-epimerase. The hexuronate C4-epimerase includes an amino acid sequence set forth in SEQ ID NO: 1, in which serine (S) at position 125, serine (S) at position 185, valine (V) at position 267, serine (S) at position 268, threonine (T) at position 272, tryptophan (W) at position 306, arginine (R) at position 386 and tyrosine (Y) at position 403 from an N-terminal of hexunorate C4-epimerase are mutated.

Claim (Index 7):
The hexuronate C4-epimerase variant according to  claim 2 , wherein a valine (V) amino acid residue at position 267 is substituted with methionine (M), a serine (S) amino acid residue at position 268 is substituted with threonine (T), and a threonine (T) amino acid residue at position 272 is further substituted with aspartic acid (D); and\n (i) a glutamine (Q) amino acid residue at position 149 is substituted with arginine (R), and an arginine (R) amino acid residue at position 386 is substituted with valine (V); (ii) a proline (P) amino acid residue at position 166 is substituted with arginine (R), and an arginine (R) amino acid residue at position 386 is substituted with valine (V); (iii) a serine (S) amino acid residue at position 185 is substituted with glutamine (Q), and a tyrosine (Y) amino acid residue at position 403 is substituted with threonine (T); or (iv) a proline (P) amino acid residue at position 351 is substituted with serine (S), and an arginine (R) amino acid residue at position 386 is substituted with valine (V).
