摘要： Provided are a mutant cis-prenyltransferase (CPT) family protein and a method for producing a polyisoprenoid, which enable the production of a high molecular weight polyisoprenoid. Included is a mutant cis-prenyltransferase (CPT) family protein obtained by mutating the amino acid sequence of a C-terminal region of a cis-prenyltransferase (CPT) family protein not found on rubber particles to be identical or similar to the amino acid sequence of a C-terminal region of a cis-prenyltransferase (CPT) family protein found on rubber particles.

摘要： The present invention provides a method for producing a polyisoprenoid, which makes it possible to synthesize in vitro a polyisoprenoid having an unprecedented structure, such as a 100% cis-polyisoprenoid or a polyisoprenoid containing an allylic diphosphate derivative as an initiating terminal. The present invention relates to a method for producing a polyisoprenoid in vitro, which employs a gene coding for a neryl diphosphate synthase and rubber particles bound to a protein encoded by the gene, or a method for producing a polyisoprenoid, which includes introducing into a plant a vector in which a gene coding for a neryl diphosphate synthase is linked to a promoter having a promoter activity that drives laticifer-specific gene expression to express a protein encoded by the gene specifically in laticifers.

摘要： The present invention aims to provide a method which, even when a protein complex is formed, can purify a protein derived from such a membrane protein complex by eluting the membrane protein complex maintaining its complex form. The present invention relates to a method for purifying a protein derived from a membrane protein complex, which includes: a protein binding step of binding to an antibody a membrane protein complex eluted from a membrane using a synthetic polymer; a protein eluting step of eluting the membrane protein complex bound to the antibody in the protein binding step at a pH of 6.0 or higher; and a synthetic polymer removing step of subjecting the membrane protein complex eluted in the protein eluting step to solvent extraction at a pH of 7.0 or lower to remove the synthetic polymer.
