Chemical Proteomics Reveals Protein Tyrosination Extends Beyond the Alpha‐Tubulins in Human Cells**

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Protein post‐translational modifications allow cells to swiftly adjust activity and localization of proteins. Here, we developed a chemical proteomic approach to determine a protein tyrosination status using an O‐propargyl tyrosine probe. We show that tyrosination modifies previously described alpha‐tubulins with ‐EEY C‐terminal sequence together with ...

Utilization of a deoxynucleoside diphosphate substrate by HIV reverse transcriptase [PDF]

, 2008
Background: Deoxynucleoside triphosphates (dNTPs) are the normal substrates for DNA sysnthesis is catalyzed by polymerases such as HIV-1 reverse transcriptase (RT).

The Interactions of Anti-HIV Pronucleotides with a Model Phospholipid Membrane

Molecules
Pronucleotides, after entering the cell, undergo chemical or enzymatic conversion into nucleotides with a free phosphate residue, and the released nucleoside 5′-monophosphate is then phosphorylated to the biologically active form, namely nucleoside 5 ...

Cladribine Analogues via O6-(Benzotriazolyl) Derivatives of Guanine Nucleosides

Molecules, 2015
Cladribine, 2-chloro-2′-deoxyadenosine, is a highly efficacious, clinically used nucleoside for the treatment of hairy cell leukemia. It is also being evaluated against other lymphoid malignancies and has been a molecule of interest for well over half a ...

Recent Advances in Molecular Mechanisms of Nucleoside Antivirals

Current Issues in Molecular Biology, 2023
The search for new drugs has been greatly accelerated by the emergence of new viruses and drug-resistant strains of known pathogens. Nucleoside analogues (NAs) are a prospective class of antivirals due to known safety profiles, which are important for ...

Mg spin affects adenosinetriphosphate activity [PDF]

PMC Physics B 2008, 1:18, 2009
The Schlegel-Frisch ab initio molecular dynamics (ADMP) (DFT:B3LYP), T = 310 K, is used to study complexation between adenosinetriphosphate (ATP), ATP subsystem, and magnesium cofactor [Mg(H2O)6]2+, Mg subsystem, in a water pool, modeled with 78 water molecules, in singlet (S) and triplet (T) states.

Cytoplasmic delivery of antibodies through grafting a functional single complementarity‐determining region loop

FEBS Letters, EarlyView.
We achieved cytoplasmic delivery of non‐cell‐penetrating IgGs by grafting a single functional complementarity‐determining region 1 (CDR1) from the light chain variable region (VL) of the cell‐internalizable 3D8 antibody. The engineered IgG acquired cell‐penetrating ability while maintaining antigen affinity, highlighting CDR1 grafting as a promising ...

A Self-Assembled Aggregate Composed of a Fatty Acid Membrane and the Building Blocks of Biological Polymers Provides a First Step in the Emergence of Protocells

Life, 2016
We propose that the first step in the origin of cellular life on Earth was the self-assembly of fatty acids with the building blocks of RNA and protein, resulting in a stable aggregate.

A Bayesian measurement error model for two-channel cell-based RNAi data with replicates [PDF]

Annals of Applied Statistics 2012, Vol. 6, No. 1, 356-382, 2012
RNA interference (RNAi) is an endogenous cellular process in which small double-stranded RNAs lead to the destruction of mRNAs with complementary nucleoside sequence. With the production of RNAi libraries, large-scale RNAi screening in human cells can be conducted to identify unknown genes involved in a biological pathway.
