Template-directed biopolymerization: tape-copying Turing machines

, 2012
DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear ...

REPARATION : ribosome profiling assisted (re-)annotation of bacterial genomes [PDF]

, 2017
Prokaryotic genome annotation is highly dependent on automated methods, as manual curation cannot keep up with the exponential growth of sequenced genomes.

Uncharged tRNA Activates GCN2 by Displacing the Protein Kinase Moiety from a Bipartite tRNA-Binding Domain [PDF]

, 2000
Protein kinase GCN2 regulates translation in amino acid–starved cells by phosphorylating eIF2. GCN2 contains a regulatory domain related to histidyl-tRNA synthetase (HisRS) postulated to bind multiple deacylated tRNAs as a general sensor of starvation ...

DKK3 Initially Preserves Acinar Integrity Through MEK‐Fos Signaling, but Later Switches to an Oncogenic Role in Pancreatic Cancer

Advanced Science, EarlyView.
In pancreatic cancer, the protein DKK3 is found to play a complex role: it initially slows early tumor growth but later promotes tumor aggressiveness. DKK3 expression evolves during progression and drives cancer severity by orchestrating cellular and molecular signaling pathways.

rRNA methyltransferases and their role in resistance to antibiotics [PDF]

Journal of Medical Biochemistry, 2010
Methyltransferases (MTases), a large protein superfamily, commonly use S-adenosyl-L-methionine (SAM) as the methyl group donor. SAM-dependant MTases methylate both nucleic acids (DNA, RNA) and proteins, and thus modulate their activity, function and ...

Dynamics of ribosomes and release factors during translation termination in E. coli

eLife, 2018
Release factors RF1 and RF2 promote hydrolysis of peptidyl-tRNA during translation termination. The GTPase RF3 promotes recycling of RF1 and RF2. Using single molecule FRET and biochemical assays, we show that ribosome termination complexes that carry ...
