PROTEIN OR POLYPEPTIDE HAVING LACHRYMATOR SYNTHASE ACTIVITY, DNA ENCODING THE PROTEIN OR THE POLYPEPTIDE, PROCESS FOR PRODUCING PROTEIN OR POLYPEPTIDE HAVING LACHRYMATOR SYNTHASE ACTIVITY USING THE DNA, AND NUCLEIC ACID MOLECULE INHIBITING THE TRANSLATION OF mRNA CONCERNING THE PROTEIN OR THE PEPTIDE

摘要

A protein or a polypeptide having an effect of converting 1-propenylsulfenic acid into a lachrymator which participates in the synthesis of the lachrymator released in grinding or cutting a plant such as onion; a DNA encoding the above protein or polypeptide (a lachrymator synthase gene); a primer to be used in isolating the lachrymator synthase gene of a plant belonging to the genus Allium; a method of isolating the gene with the use of the primer; a recombinant vector containing the above DNA; a transformant having a recombinant vector containing the above DNA; a process for producing a protein or a polypeptide having the lachrymator synthase activity by culturing host cells having been transformed by a recombinant vector containing the above DNA; a protein or a polypeptide having the lachrymator synthase activity; and a nucleic acid molecule inhibiting the translation of mRNA concerning a protein or a polypeptide having the lachrymator synthase activity.
