...In the former case, a protein called a repressor suppresses the expression of genes such as β-galactosidase, but when lactose is present in the environment, lactose binds to the repressor and the suppression of gene transcription is released. This is called enzyme induction, and substances such as lactose are called inducers. However, when lactose and glucose coexist in the culture medium, enzyme induction does not occur, glucose is consumed, and lactose remains as it is. ... *Some terminology explanations that mention "inducer" are listed below.

…前者の場合,リプレッサーと呼ばれるタンパク質がβ‐ガラクトシダーゼなどの遺伝子発現を抑制しているが,ラクトースが環境中に存在する場合,ラクトースとリプレッサーが結合し遺伝子転写の抑制が解除される。これを酵素の誘導といい,ラクトースのような物質を誘導物質inducerと呼ぶ。ところで,ラクトースとグルコースが培養液中に共存している場合,酵素の誘導は起こらずもっぱらグルコースが消費され,ラクトースはそのまま残る。… ※「inducer」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
