Abstract: The present invention provides a heterojunction photocatalyst having higher photocatalytic activity than that of a conventional heterojunction photocatalyst. Further, the present invention provides a photocatalyst composite having the heterojunction photocatalyst on a substrate, a method for producing the heterojunction photocatalyst, and a method for producing hydrogen using the heterojunction photocatalyst or the photocatalyst composite The het junction photocatalyst of the present invention has a solid mediator between a hydrogen-evolution photocatalyst and an oxygen-evolution photocatalyst, and the solid mediator is selectively joined to an electrons collecting surface of the oxygen-evolution photocatalyst.

Abstract: Provided is a method for producing a heavy chain variable domain of a heavy-chain antibody (VHH) with a high yield. The method for producing a VHH includes culturing a Bacillus bacterium into which a gene that encodes variable domain of heavy chain of heavy-chain antibody is introduced and which is deficient in an extracellular protease.

Abstract: The present disclosure provides a gene encoding a protein having ?-ketoacyl-ACP synthase activity having at least 60% or more identity with the amino acid sequence set forth in SEQ ID NO:1, the protein encoded by the gene, a method of producing a transformant by transforming a host with the gene, a transformant that is transformed with the gene, and a method of producing a lipid, especially, a lipid containing a medium chain fatty acid or ester thereof, by culturing the transformed host that expresses the gene. In some embodiments, the transformant also has a gene encoding an acyl-ACP thioesterase.

Abstract: [Problems] To provide a method of producing a medium chain fatty acid or a lipid containing this fatty acid as a component by using a ?-ketoacyl-ACP synthase, and a gene, a protein and a transformant for use in this method. [Means to solve] A method of producing a medium chain fatty acid or a lipid containing this fatty acid as a component, containing the steps of: introducing a gene encoding the following protein (A) or (B) into a host, and thereby obtaining a transformant, and collecting a medium chain fatty acid or a lipid containing this fatty acid as a component from the resulting transformant; and a gene, a protein and a transformant for use in this method: (A) A protein consisting of the amino acid sequence set forth in SEQ ID NO: 1; and (B) A protein consisting of an amino acid sequence having 90% or more identity with the amino acid sequence set forth in SEQ ID NO: 1, and having medium chain acyl-ACP-specific ?-ketoacyl-ACP synthase activity.

Abstract: A method of producing a lipid, containing the following steps (1) and (2); and a transformant obtained by introducing a gene encoding the following protein (a) or (b) into a host: (1) introducing a gene encoding the following protein (a) or (b) into a host, and thereby obtaining a transformant, and (2) collecting a lipid from the resulting transformant: (a) A protein consisting of an amino acid sequence set forth in SEQ ID NO: 1; and (b) A protein consisting of an amino acid sequence having 60% or more identity with the amino acid sequence of the protein (a), and having ?-ketoacyl-ACP synthase activity.

Abstract: A method of producing a fatty acid or a lipid containing a fatty acid, using a thioesterase variant having an amino acid sequence in which the 231st amino acid is substituted from threonine to lysine in the amino acid sequence set forth in SEQ ID NO: 1; and a transformant obtained by introducing a gene that encodes the thioesterase variant which transformant has an enhanced ability to produce a fatty acid or a lipid containing a fatty acid.
