MutS-mediated enrichment of mutated DNA produced by directed evolution in vitro.

World journal of microbiology & biotechnology

Zhong T, Zhou Y, Bi L, Zhang XE.
PMID: 25187136
World J Microbiol Biotechnol. 2011 Jun;27(6):1367-72. doi: 10.1007/s11274-010-0587-0. Epub 2010 Oct 10.

Directed evolution in vitro is a powerful tool in the study and design of protein function. However, screening the desired mutants is a difficult task. To facilitate the screening, a method is proposed to eliminate wild type sequences and...

A Coarse Grained Model for Atomic-Detailed DNA Simulations with Explicit Electrostatics.

Journal of chemical theory and computation

Dans PD, Zeida A, Machado MR, Pantano S.
PMID: 26615701

Coarse-grain (CG) techniques allow considerable extension of the accessible size and time scales in simulations of biological systems. Although many CG representations are available for the most common biomacromolecules, very few have been reported for nucleic acids. Here, we...

Irreversible inhibitors of the 3C protease of Coxsackie virus through templated assembly of protein-binding fragments.

Nature communications

Becker D, Kaczmarska Z, Arkona C, Schulz R, Tauber C, Wolber G, Hilgenfeld R, Coll M, Rademann J.
PMID: 27677239
Nat Commun. 2016 Sep 28;7:12761. doi: 10.1038/ncomms12761.

Small-molecule fragments binding to biomacromolecules can be starting points for the development of drugs, but are often difficult to detect due to low affinities. Here we present a strategy that identifies protein-binding fragments through their potential to induce the...

An efficient two-step subcellular fractionation method for the enrichment of insulin granules from INS-1 cells.

Biophysics reports

Chen Y, Xia Z, Wang L, Yu Y, Liu P, Song E, Xu T.
PMID: 26942217
Biophys Rep. 2015;1:34-40. doi: 10.1007/s41048-015-0008-x. Epub 2015 Aug 07.

Insulin is one of the key regulators for blood glucose homeostasis. More than 99% of insulin is secreted from the pancreatic β-cells. Within each β-cell, insulin is packaged and processed in insulin secretary granules (ISGs) before its exocytosis. Insulin...

Proteins as templates for complex synthetic metalloclusters: towards biologically programmed heterogeneous catalysis.

Proceedings. Mathematical, physical, and engineering sciences

Fehl C, Davis BG.
PMID: 27279776
Proc Math Phys Eng Sci. 2016 May;472(2189):20160078. doi: 10.1098/rspa.2016.0078.

Despite nature's prevalent use of metals as prosthetics to adapt or enhance the behaviour of proteins, our ability to programme such architectural organization remains underdeveloped. Multi-metal clusters buried in proteins underpin the most remarkable chemical transformations in nature, but...

Multi-Level Interactions Between Heat Shock Factors, Heat Shock Proteins, and the Redox System Regulate Acclimation to Heat.

Frontiers in plant science

Driedonks N, Xu J, Peters JL, Park S, Rieu I.

Front Plant Sci. 2015 Nov 17;6:999. doi: 10.3389/fpls.2015.00999. eCollection 2015.

High temperature has become a global concern because it seriously affects the growth and reproduction of plants. Exposure of plant cells to high temperatures result in cellular damage and can even lead to cell death. Part of the damage...

Encapsulation of Inorganic Nanomaterials inside Virus-Based Nanoparticles for Bioimaging.

Nanotheranostics

Zhang W, Xu C, Yin GQ, Zhang XE, Wang Q, Li F.
