Target-switch SELEX: Screening with alternating targets to generate aptamers to conserved terminal dipeptides

open access: yesSTAR Protocols, 2022
Summary: Systematic evolution of ligands by exponential enrichment (SELEX) encompasses a wide variety of high-throughput screening techniques for producing nucleic acid binders to molecular targets through directed evolution.

Exploring Protein Sequence Space Using Computationally Directed Recombination [PDF]

open access: yes, 2006
Evolution has provided us with many protein sequences. However, these sequences represent a very small fraction of the possible sequences. In the laboratory, scientists have explored areas of sequence space not represented by natural proteins both to ...

Prediction of Thermostability of Enzymes Based on the Amino Acid Index (AAindex) Database and Machine Learning

open access: yesMolecules, 2023
The combination of wet-lab experimental data on multi-site combinatorial mutations and machine learning is an innovative method in protein engineering. In this study, we used an innovative sequence-activity relationship (innov’SAR) methodology based on ...

The Remarkable Evolutionary Plasticity of Coronaviruses by Mutation and Recombination: Insights for the COVID-19 Pandemic and the Future Evolutionary Paths of SARS-CoV-2

open access: yesViruses, 2022
Coronaviruses (CoVs) constitute a large and diverse subfamily of positive-sense single-stranded RNA viruses. They are found in many mammals and birds and have great importance for the health of humans and farm animals. The current SARS-CoV-2 pandemic, as

Big and Slow: Phylogenetic estimates of molecular evolution in baleen whales (Suborder Mysticeti).

open access: yes, 2009
Published in a leading journal of molecular evolutionary, this article presents the largest databases available to date of mitochondrial and nuclear intron sequences to estimate the ‘neutral’ rate of molecular evolution in the largest species of animals ...

Recent progress in directed evolution of stereoselective monoamine oxidases

open access: yesBioresources and Bioprocessing, 2019
Monoamine oxidases (MAOs) use molecular dioxygen as oxidant to catalyze the oxidation of amines to imines. This type of enzyme can be employed for the synthesis of primary, secondary, and tertiary amines by an appropriate deracemization protocol ...

Optimized expression and specific activity of IL-12 by directed molecular evolution [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
DNA delivery of IL-12 has shown promise in reducing the toxic side effects associated with administration of recombinant human (h)IL-12 protein while maintaining the ability to inhibit tumor growth and abolish tumor metastases in animal models. We have developed a more potent version of IL-12 by using DNA shuffling and screening to improve its ...

Comparative Analysis of Bacteriophytochrome Agp2 and Its Engineered Photoactivatable NIR Fluorescent Proteins PAiRFP1 and PAiRFP2

open access: yesBiomolecules, 2020
Two photoactivatable near infrared fluorescent proteins (NIR FPs) named “PAiRFP1” and “PAiRFP2” are formed by directed molecular evolution from Agp2, a bathy bacteriophytochrome of Agrobacterium tumefaciens C58.

Molecular dynamics simulation of an entire cell

open access: yesFrontiers in Chemistry, 2023
The ultimate microscope, directed at a cell, would reveal the dynamics of all the cell’s components with atomic resolution. In contrast to their real-world counterparts, computational microscopes are currently on the brink of meeting this challenge.
