Conformational dynamics in TRPV1 channels reported by an encoded coumarin amino acid

open access: yeseLife, 2017
TRPV1 channels support the detection of noxious and nociceptive input. Currently available functional and structural data suggest that TRPV1 channels have two gates within their permeation pathway: one formed by a ′bundle-crossing′ at the intracellular ...

Human-specific transcriptional regulation of CNS development genes by FOXP2. [PDF]

open access: yes, 2009
The signalling pathways controlling both the evolution and development of language in the human brain remain unknown. So far, the transcription factor FOXP2 (forkhead box P2) is the only gene implicated in Mendelian forms of human speech and language ...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains [PDF]

open access: yes, 2009
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology ...

A designed phenylalanyl-tRNA synthetase variant allows efficient in vivo incorporation of aryl ketone functionality into proteins [PDF]

open access: yes, 2002
Incorporation of non-natural amino acids into proteins in vivo expands the scope of protein synthesis and design. p-Acetylphenylalanine was incorporated into recombinant dihydrofolate reductase (DHFR) in Escherichia coli via a computationally designed ...

Expanding the genetic code: phage-driven evolution of pyrrolysyl-synthetase for site-specific incorporation of synthetic phenylalanine and tyrosine derivatives

open access: yesFrontiers in Molecular Biosciences
IntroductionPyrrolysyl-tRNA synthetase (PylRS) is a key enzyme for the site-specific incorporation of non-canonical amino acids (ncAAs) into proteins. However, its native form has a limited substrate scope.

Chimeric Translation for Mitochondrial Peptides: Regular and Expanded Codons

open access: yesComputational and Structural Biotechnology Journal, 2019
Frameshifting protein translation occasionally results from insertion of amino acids at isolated mono- or dinucleotide-expanded codons by tRNAs with expanded anticodons.

Asymmetric synthesis of fluorinated derivatives of aromatic and γ-branched amino acids via a chiral Ni(II) complex

open access: yesBeilstein Journal of Organic Chemistry
Fluorinated amino acids are essential building blocks in the spheres of protein engineering and medicinal chemistry. In the last decades, a large number of different synthetic strategies have been developed to produce a large variety of fluorinated amino

pH dependence of charge multipole moments in proteins

open access: yes, 2017
Electrostatic interactions play a fundamental role in the structure and function of proteins. Due to ionizable amino acid residues present on the solvent-exposed surfaces of proteins, the protein charge is not constant but varies with the changes in the ...

The Application of Cell-Free Protein Synthesis in Genetic Code Expansion for Post-translational Modifications

open access: yesFrontiers in Pharmacology, 2019
The translation system is a sophisticated machinery that synthesizes proteins from 20 canonical amino acids. Recently, the repertoire of such composition has been expanded by the introduction of non-canonical amino acids (ncAAs) with the genetic code ...

Monitoring Replication Protein A (RPA) Dynamics in Homologous Recombination Through Site-specific Incorporation of Non-canonical Amino Acids [PDF]

open access: yes, 2017
An essential coordinator of all DNA metabolic processes is Replication Protein A (RPA). RPA orchestrates these processes by binding to single-stranded DNA (ssDNA) and interacting with several other DNA binding proteins. Determining the real-time kinetics
