4.1 The Operon Model of Gene Regulation An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes. The genes in an operon are ...
Bistability arises in the lac operon model as the external lactose (Le) concentration changes when μ = 2.26 × 10− 2 min− 1. Notice that the parameter values, there exists a range of Le concentration for which there are three coexisting steady states for β-galactosidase concentration. ...

Deterministic and stochastic simulation of the Yildirim–Mackey lac operon model given by Eqs. (12.25)–(12.29). In this simulation, the solid lines show the ODE solutions and the broken lines represent the results of the stochastic simulations. To produce this plot, we chose the steady state ...
This control involves regulation by several components which interact with genetic material at distinct locations within the lac operon. This interaction is influenced by several low molecular weight compounds whose concentration modulates the expression of the operon. The model described for β-...
The lactosepermeaseis a good transport system with which to transition from passive transport to active transport.45Thelactose permeasefromE. coli(lacY, a structural gene in thelacoperon) is a member of theMFS. UnlikeGLUT1, also a member of the MFS, the lactose permease engages in active tran...
The lactose operon (lacTEGF) from Lactobacillus casei strain BL23 has been previously studied. The lacT gene codes for a transcriptional antiterminator, lacE and lacF for the lactose-specific phosphoenolpyruvate: phosphotransferase system (PTSLac) EIICB
