Comparison of deterministic and stochastic models of the lac operon genetic network. [PDF]
Biophys J, 2009 The lac operon has been a paradigm for genetic regulation with positive feedback, and several modeling studies have described its dynamics at various levels of detail.

Stochastic stability and observer design for the lac operon model
, 2015 The aim of this study is to investigate the stability properties of a model of the lac operon enhanced with stochastic perturbations. New sufficient conditions of exponential mean square stability are obtained analytically for this model and threshold ...

The impact of metabolism on the adaptation of organisms to environmental change
Frontiers in Cell and Developmental Biology, 2023 Since Jacob and Monod’s discovery of the lac operon ∼1960, the explanations offered for most metabolic adaptations have been genetic. The focus has been on the adaptive changes in gene expression that occur, which are often referred to as “metabolic ...

Protein Science, Volume 35, Issue 6, June 2026.Abstract Zinc finger proteins are essential for the proper functioning of eukaryotic organisms, while their artificial variants can be used in cancer therapy or gene editing via their specific DNA recognition. Zn(II) binding is indispensable for the structural integrity of zinc fingers.

Frontiers in Microbiology, 2019 Biofilm formation by Klebsiella pneumoniae on indwelling medical devices increases the risk of infection. Both type 1 and type 3 fimbriae are important factors in biofilm formation by K. pneumoniae. We found that a putative enzyme II (EII) complex of the

The lac operon galactoside acetyltransferase
Comptes Rendus. Biologies, 2005 Of the proteins encoded by the three structural genes of the lac operon, the galactoside acetyltransferase (thiogalactoside transacetylase, LacA, GAT) encoded by lacA is the only protein whose biological role remains in doubt.

Microbial Biotechnology, Volume 19, Issue 6, June 2026.Pseudomonas putida KT2440 grows on polyethylene‐derived long‐chain alcohols (C16OH, C20OH) as sole carbon sources. Adaptive laboratory evolution rapidly increases growth, converging on envelope‐associated mutations. Expressing the outer‐membrane transporter AlkL recapitulates much of the evolved phenotype, identifying substrate access and membrane ...
