N-TERMINAL PROCESSING OF RIBOSOMAL PROTEIN L27 IN STAPHYLOCOCCUS AUREUS [PDF]

open access: yes, 2012
The bacterial ribosome is essential to cell growth yet little is known about how its proteins attain their mature structures. Recent studies indicate that certain Staphlyococcus aureus bacteriophage protein sequences contain specific sites that may be ...

Protein-protein interface analysis of the non-ribosomal peptide synthetase peptidyl carrier protein and enzymatic domains

open access: yesSynthetic and Systems Biotechnology, 2022
Non-ribosomal peptide synthetases (NRPSs) are attractive targets for biosynthetic pathway engineering due to their modular architecture and the therapeutic relevance of their products.

Nascent polypeptide chains exit the ribosome in the same relative position in both eucaryotes and procaryotes. [PDF]

open access: yes, 1983
We located the polypeptide nascent chain as it leaves cytoplasmic ribosomes from the plant Lemna gibba by immune electron microscopy using antibodies against the small subunit of the enzyme ribulose-1,5-bisphosphate carboxylase.

Translation termination depends on the sequential ribosomal entry of eRF1 and eRF3.

open access: yes, 2019
Translation termination requires eRF1 and eRF3 for polypeptide-and tRNA-release on stop codons. Additionally, Dbp5/DDX19 and Rli1/ABCE1 are required; however, their function in this process is currently unknown.

The Central Symbiosis of Molecular Biology: Molecules in Mutualism. [PDF]

open access: yes, 2017
As illustrated by the mitochondrion and the eukaryotic cell, little in biology makes sense except in light of mutualism. Mutualisms are persistent, intimate, and reciprocal exchanges; an organism proficient in obtaining certain benefits confers those on ...

Ribozyme für die RNA‐katalysierte Methylierung und Markierung von RNA

open access: yesAngewandte Chemie, EarlyView.
Ribozyme sind vielseitige Werkzeuge für die präzise Modifikation von RNA. Das Reaktionsspektrum in‐vitro‐selektierter Ribozyme reicht vom Einbau funktioneller Gruppen und Fluorophoren bis zu natürlichen RNA‐Methylierungen. Dieser Übersichtsartikel präsentiert Cofaktor‐abhängige Ribozyme für die positionsgenaue Markierung und Modifikation von RNA ...

tRNA Core Hypothesis for the Transition from the RNA World to the Ribonucleoprotein World

open access: yesLife, 2016
Herein we present the tRNA core hypothesis, which emphasizes the central role of tRNAs molecules in the origin and evolution of fundamental biological processes.

Identification of the prebiotic translation apparatus within the contemporary ribosome [PDF]

open access: yes, 2009
A structural element that could have existed independently in the prebiotic era was identified at the active site of the contemporary ribosome. It is suggested to have functioned as a proto-ribosome catalyzing peptide bond formation and non-coded ...

Mutations in the bacterial ribosomal protein l3 and their association with antibiotic resistance [PDF]

open access: yes, 2015
Different groups of antibiotics bind to the peptidyl transferase center (PTC) in the large subunit of the bacterial ribosome. Resistance to these groups of antibiotics has often been linked with mutations or methylations of the 23S rRNA. In recent years,

Directed evolution of the rRNA methylating enzyme Cfr reveals molecular basis of antibiotic resistance

open access: yeseLife, 2022
Alteration of antibiotic binding sites through modification of ribosomal RNA (rRNA) is a common form of resistance to ribosome-targeting antibiotics. The rRNA-modifying enzyme Cfr methylates an adenosine nucleotide within the peptidyl transferase center,
