    Abstract: A method of identifying an antifungal agent which targets a DHODH protein (alias PyrE, dihydroorotate dehydrogenase, EC: 1.3.99.11) of a fungus comprising contacting a candidate substance with a fungal DHODH protein and determining whether the candidate substance binds or modulates the DHODH protein, wherein binding or modulation indicates that the candidate substance is an antifungal agent. Specific examples concern Aspergillus fumigatus and Candida albicans DHODH proteins. DHODH inhibitors with a Quinazolinone core are also disclosed.

  • Patent number: 9005937
    Abstract: There are provided a novel ribitol dehydrogenase, a residue determining double coenzyme specificity, and a method for preparing L-ribulose using the same, and more particularly, to a ribitol dehydrogenase producing rare sugars, nucleic acid molecules encoding the same, a vector including the nucleic acid molecules, a transformant including the vector, a mutant of the ribitol dehydrogenase, and a method for preparing L-ribulose using the ribitol dehydrogenase. The ribitol dehydrogenase having double coenzyme specificity, which is derived from Zymomonas mobilis, can effectively be used for preparing high-priced rare sugars and an investigation of coenzyme specificity determinants for the ribitol dehydrogenase is applied for all of dedydrogenases as a based technique.

  • Patent number: 8999691
    Abstract: Disclosed is a modified glucose dehydrogenases that has dramatically increased productivity in Escherichia coli and dramatically increased thermal stability, which is obtained by introducing specific amino acid mutations to glucose dehydrogenase derived from Botryotinia fuckeliana. Also disclosed is a modified glucose dehydrogenases that has dramatically increased productivity in E. coli and dramatically increased thermal stability, which is obtained by replacing two amino acid residues in glucose dehydrogenase of fungal origin with cysteine residues. The novel glucose dehydrogenase has a low reactivity to xylose.
