Expression regulation of bacterial lipase genes: a review

Frontiers in Microbiology
Microbial lipases constitute the primary source of commercialized and industrial lipases, and they are extensively utilized across numerous industrial sectors. Compared to fungal lipases, bacterial lipases catalyze a broader spectrum of reactions with higher activity, enhanced stability, and improved stress resistance.

Regulation of asymmetries in the kinetics and protein numbers of bacterial gene expression

Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2019
Genetic circuits change the status quo of cellular processes when their protein numbers cross thresholds. We investigate the regulation of RNA and protein threshold crossing propensities in Escherichia coli. From in vivo single RNA time-lapse microscopy data from multiple promoters, mutants, induction schemes and media, we study the asymmetry and ...

Use of Bacterial Quorum-Sensing Components to Regulate Gene Expression in Plants   [PDF]

Plant Physiology, 2006
Abstract We describe an efficient inducible system to regulate gene expression in plants based on quorum-sensing components found in Gram-negative bacteria such as Agrobacterium tumefaciens. These bacteria monitor their own population density by utilizing members of the N-acyl homoserine lactone family as inducers and a transcriptional ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Rhythmic diel pattern of gene expression in juvenile maize leaf. [PDF]

, 2011
Co-expressed genes belonging to individual clusters are likely to be regulated by common mechanisms. The nocturnal phase of the diurnal cycle involves gross induction of fundamental biochemical processes and should be studied more thoroughly than was ...

Regulation of bacterial gene expression by the NTP substrates of transcription initiation [PDF]

Molecular Microbiology, 2008
SummaryMany mechanisms of gene regulation in bacteria do not employ repressor or activator proteins. One class of these mechanisms includes those in which the key regulatory element is the control of transcription initiation by the availability of NTP substrates.

Lithium-sensing riboswitch classes regulate expression of bacterial cation transporter genes

Scientific Reports, 2022
AbstractLithium is rare in Earth’s crust compared to the biologically relevant alkali metal cations sodium and potassium but can accumulate to toxic levels in some environments. We report the experimental validation of two distinct bacterial riboswitch classes that selectively activate gene expression in response to elevated Li+ concentrations.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
