This type of regulation is called negative regulation, since it employs a repression to prevent transcription. The use of activator proteins in the positive control of gene expression is also common in prokaryotes. In this system, the activator protein promotes transcription. Positive Control.
Groups of genes coding for related proteins are arranged in units known as operons. An operon consists of an operator, promoter, regulator, and structural genes. The regulator gene codes for a repressor protein that binds to the operator, obstructing the promoter (thus, transcription) of the structural genes. The regulator does not have to be adjacent to other genes in the operon. If the repressor protein is removed, transcription may occur.
