The genes and important sequences for the regulation of the lac operon are organized such that several mediators can fine tune expression of the three genes in the operon itself—lacZ, lacY, and ...

The genes lacZ, lacY and lacA are transcribed from a single promoter (P) that produces a single mRNA from which the three proteins are translated. The operon is regulated by Lac repressor ...

Microbial genes, including cntA/B, the cai operon, and the gbu gene cluster, have been implicated in converting L-carnitine into TMA(O). However, the key genes and microbes remain underexplored.

How do bacteria avoid wasteful production of unnecessary proteins when their genes are always on? The answer lies in regulating the operon. As trp levels increase, trp binds to trpR, causing a ...
