The pho regulons of bacteria
Webb26 mars 2024 · Regulons, were previously identified in bacteria as well, where a cluster of operons named as a regulon. At present, a regulon is a DNA fragment or a genetic unit that is under the control of a common regulatory gene. Therefore, more than the promoter and the operator, a new regulator gene is involved in regulon gene expression.

WebbOperons are common in bacteria, but they are rare in eukaryotes such as humans. In general, an operon will contain genes that function in the same process. For instance, a well-studied operon called the lac operon contains genes that encode proteins involved in uptake and metabolism of a particular sugar, lactose.

Commonly studied regulons in bacteria are those involved in response to stress such as heat shock. The heat shock response in E. coli is regulated by the sigma factor σ32 (RpoH), whose regulon has been characterized as containing at least 89 open reading frames.
