摘要:
Provided is a preventive and/or therapeutic agent for malaria, comprising, as an active ingredient, 5-acetamido-4-oxo-5-hexenoic acid (Alaremycin) or a derivative thereof. A preventive and/or therapeutic agent for malaria is used which comprises, as an active ingredient, Alaremycin or a derivative thereof represented by formula (I) (wherein R1 represents a hydroxy group, an amino group, or a substituted or unsubstituted straight chain or branched alkoxy group or alkylamino group having 1 to 8 carbons; R2 represents hydrogen, a substituted or unsubstituted straight chain or branched alkyl group having 1 to 8 carbons, or a substituted or unsubstituted aromatic group having 4 to 10 carbons; and R3 represents hydrogen or a methyl group).
摘要:
The present invention relates to a penicillin binding protein, DNA encoding the protein and methods of producing L-glutamic acid in Corynebacterium glutamicum, which has a reduction of penicillin binding protein activity.
摘要:
The identification of MreB as essential for bacterial chromosome segregation provides a new target for antibiotic action. The MreB function is useful in the development of screening assays for new antibiotics, which may use, for example, genetic mutants in MreB, tests of MreB mediated chromosome segregation, and the like. In one embodiment of the invention, the antibiotic is an isothiourea compound, which may comprise a polyhalogenated benzyl group, e.g. at the 4 position, the 2,4 position, etc. A pharmaceutical composition comprising an MreB targeted antibiotic as an active agent is administered to a patient suffering from a microbial infection, particularly bacterial infections.

The present invention relates to a protein having an activity of giving a lysozyme insensitivity to a lysozyme-sensitive microorganism belonging to Corynebacterium glutamicum; DNA which codes for the protein; a recombinant vector containing the DNA; a transformant obtained by introducing the recombinant vector into a host cell; a bacterium having a lysozyme sensitivity in which the activity of the protein is inactivated; and a method for producing an amino acid using the bacterium.

摘要:
The present invention relates to a polypeptide having the activity of N-acetylglucosamine-1-phosphate uridyltransferase (hereinafter referred to as GlmU), a DNA coding for the polypeptide, a recombinant DNA containing the DNA, a transformant carrying the recombinant DNA, a method of culturing the transformant for producing the GlmU polypeptide, and a method of culturing the transformant for producing uridine 5′-diphosphate-N-acetylglucosamine.According to the present invention, mass-scale production of the GlmU polypeptide derived from microorganisms belonging to the genus Corynebacterium glutamicum has been enabled by genetic recombinant technology. By using the enzyme, uridine 5′-diphosphate-N-acetylglucosamine can be produced efficiently.
