摘要:
Provided is a radiotherapeutic agent, including a composite particle, which is obtained by binding a molecule that specifically recognizes a target to a substrate particle including titanium peroxide, and which generates reactive oxygen through irradiation with a radiation. Further, because the radiotherapeutic agent contains the molecule that specifically recognizes a target, the radiotherapeutic agent has a function of accumulating in the target. The radiotherapeutic agent is capable of enhancing effects of radiotherapy, and is capable of reducing side effects on a living body to efficiently attack the target.

The present invention provides a method for producing a useful substance efficiently from cellulose without using any cellulase preparation. According to the disclosures of the present specification, in the production of a useful substance from a cellulose-containing material, the cellulose-containing material is brought into contact with an ionic liquid to cause the ionic liquid to permeate the cellulose-containing material, and a carbon source comprising the cellulose in the cellulose-containing material is simultaneously saccharified and fermented by a cellulase-producing microorganism in the presence of the ionic liquid.

Provided is a microorganism that can display, on the cell surface, any molecules other than a molecule comprising amino acids, more specifically, a microorganism that displays biotin on a cell surface. The microorganism is capable of co-expressing a biotinylating enzyme and an acceptor peptide having a sequence recognized by the biotinylating enzyme, wherein the acceptor peptide is expressed on the cell surface, so that lysine of the acceptor peptide is biotinylated to display biotin on the cell surface. Also provided is a method for displaying an intended molecule, including not only a molecule comprising amino acids but also any molecules, on a cell surface of a microorganism.

The present invention provides a method for producing ethanol, including: subjecting a cellulose-based material to a hot-water treatment and an ammonia treatment to obtain a fermentation substrate; and reacting the fermentation substrate with a yeast to produce ethanol. The present invention also provides a method for producing a fermentation substrate for ethanol production by a yeast, including: subjecting a cellulose material to a hot-water treatment and an ammonia treatment to obtain a fermentation substrate. Thus obtained fermentation substrate can enhance the ethanol production by yeast.
摘要:
A plasmid is constructed so as to express a fused protein of a sugar chain-binding protein domain with a desired protein. Then this plasmid is transferred into cells and thus the protein is expressed in the cell surface layer. This method is particularly adequate in case of expressing a protein having an activity in the C-terminal portion in cell surface layer.

The invention provides hollow nanoparticles of a protein with the ability to recognize specific cells such as the hepatocytes and to form particles (for example, hepatitis B virus surface-antigen protein), wherein the protein has a cysteine residue substituted to a different amino acid. The hollow nanoparticles have a stable particle structure and can be used to efficiently transfer substances to specific target cells or tissues. The invention also provides a drug using the hollow nanoparticles.
