Enzyme annotation for orphan and novel reactions using knowledge of substrate reactive sites

Ljubisa Miskovic, Vassily Hatzimanikatis, Noushin Hadadi, Marianne Seijo

Thousands of biochemical reactions with characterized activities are “orphan,” meaning they cannot be assigned to a specific enzyme, leaving gaps in metabolic pathways. Novel reactions predicted by pathway-generation tools also lack associated sequences, l ...

Control Theory Concepts for Modeling Uncertainty in Enzyme Kinetics of Biochemical Networks

Ljubisa Miskovic, Vassily Hatzimanikatis, Georgios Savoglidis, Milenko Tokic

Analysis of the dynamic and steady-state properties of biochemical networks hinges on information about the parameters of enzyme kinetics. The lack of experimental data characterizing enzyme activities and kinetics along with the associated uncertainties i ...

Sexual conflict drives male manipulation of female postmating responses in Drosophila melanogaster

Laurent Keller, Brian Dennis Hollis

In many animals, females respond to mating with changes in physiology and behavior that are triggered by molecules transferred by males during mating. In Drosophila melanogaster, proteins in the seminal fluid are responsible for important female postmating ...

Engineered peptide macrocycles can inhibit matrix metalloproteinases with high selectivity

Christian Heinis, Jeremy Touati, Maola Khan Mohammad Golam, Michal Sabisz, Alice Baumann, Jonas Alfred Karl Wilbs, Xudong Kong, Kaycie Marie Butler

Matrix metalloproteinases (MMPs) are zinc‐dependent endopeptidases at the intersection of health and disease due to their involvement in processes such as tissue repair and immunity as well as cancer and inflammation. Because of the high structural conserv ...

RADX: A novel single-stranded DNA-binding protein regulating telomere recombination

Anna-Sophia Briod

Telomeres are specialized nucleoprotein structures present at the ends of linear chromosome. The telomeric DNA part is comprised of 5-15 kilo base pairs of double stranded TTAGGG repeats and it contains at the 3' end a single-stranded G-rich overhang of 50 ...

Linking a mutation to survival in wild mice

Jeffrey David Jensen, Matthieu Foll, Stefan Jean Laurent, Susanne Petra Pfeifer

Adaptive evolution in new or changing environments can be difficult to predict because the functional connections between genotype, phenotype, and fitness are complex. Here, we make these explicit connections by combining field and laboratory experiments i ...

The evolution of multiple active site configurations in a designed enzyme

Dusan Petrovic, Ganna Gryn'ova

Developments in computational chemistry, bioinformatics, and laboratory evolution have facilitated the de novo design and catalytic optimization of enzymes. Besides creating useful catalysts, the generation and iterative improvement of designed enzymes can ...

Photoinduced disinfection in sunlit natural waters: Measurement of the second order inactivation rate constants between E-coli and photogenerated transient species

César Pulgarin, Jean Arnaud Troyon, Stefanos Giannakis

This work uncovers the implications of the estimation of exogenous inactivation rates for E. coli after the initial lag phase, and presents a strategy for the determination of the second-order inactivation rate constants (k2nd) of these bacteria with relev ...

Single Live Cell Monitoring of Protein Turnover Reveals Intercellular Variability and Cell-Cycle Dependence of Degradation Rates

Felix Naef, Eric Paquet, David Michael Suter, Martina Biserni, Andrea Brigitta Alber

Cells need to reliably control their proteome composition to maintain homeostasis and regulate growth. How protein synthesis and degradation interplay to control protein expression levels remains unclear. Here, we combined a tandem fluorescent timer and pu ...

Dynamic protein-chromatin interactions in heterochromatin and during the DNA damage response on the single molecule level

Andreas Linus Bachmann

Dynamic regulation of chromatin, a structure consisting of DNA and histone proteins, is mediated through histone post-translational modifications (PTMs) and effector proteins. HP1a and PRC2 are recruited to repressive PTMs (H3K9me3, H3K27me3) and enable he ...
