Medical Countermeasures against Ricin Intoxication

open access: yesToxins, 2023
Ricin toxin is a disulfide-linked glycoprotein (AB toxin) comprising one enzymatic A chain (RTA) and one cell-binding B chain (RTB) contained in the castor bean, a Ricinus species.

Control of translation elongation in health and disease

open access: yesDisease Models & Mechanisms, 2020
Regulation of protein synthesis makes a major contribution to post-transcriptional control pathways. During disease, or under stress, cells initiate processes to reprogramme protein synthesis and thus orchestrate the appropriate cellular response. Recent

Further Evidence that Elongation Factor 1 Remains Bound to Ribosomes during Peptide Chain Elongation [PDF]

open access: yesEuropean Journal of Biochemistry, 1977
This paper describes three types of experiments which indicate that the binding sites for elongation factor 1 (EF‐1) and elongation factor 2 (EF‐2) on ascites cell ribosomes are not identical and perhaps not even overlapping. The experimental evidence presented includes direct competitive binding of labeled elongation factors to ribosomes as well as ...

A LytM-Domain Factor, ActS, Functions in Two Distinctive Peptidoglycan Hydrolytic Pathways in E. coli

open access: yesFrontiers in Microbiology, 2022
Bacterial cell wall contains peptidoglycan (PG) to protect the cells from turgor and environmental stress. PG consists of polymeric glycans cross-linked with each other by short peptide chains and forms an elastic mesh-like sacculus around the ...

Localized inhibition of protein phosphatase 1 by NUAK1 promotes spliceosome activity and reveals a MYC-sensitive feedback control of transcription. [PDF]

open access: yes, 2020
Deregulated expression of MYC induces a dependence on the NUAK1 kinase, but the molecular mechanisms underlying this dependence have not been fully clarified.

Specific peptide-activated proteolytic cleavage of Escherichia coli elongation factor Tu [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Phage exclusion is a form of programmed cell death in prokaryotes in which death is triggered by infection with phage, a seemingly altruistic response that limits multiplication of the phage and its spread through the population. One of the best-characterized examples of phage exclusion is the exclusion of T-even phages such as T4 by the ...

Kinetics of initiating polypeptide elongation in an IRES-dependent system

open access: yeseLife, 2016
The intergenic IRES of Cricket Paralysis Virus (CrPV-IRES) forms a tight complex with 80S ribosomes capable of initiating the cell-free synthesis of complete proteins in the absence of initiation factors. Such synthesis raises the question of what effect

Atrioventricular Conduction Abnormalities in Multisystem Inflammatory Syndrome in Children

open access: yesCase Reports in Pediatrics, 2021
Cardiac manifestations in multisystem inflammatory syndrome in children (MIS-C) can include coronary artery aneurysms, left ventricular systolic dysfunction, and electrocardiographic disturbances.

Tomato EF-Tsmt, a functional mitochondrial translation elongation factor from higher plants [PDF]

open access: yes, 2003
Ethylene-induced ripening in tomato (Lycopersicon esculentum) resulted in the accumulation of a transcript designated LeEF-Tsmt that encodes a protein with significant homology to bacterial Ts translational elongation factor (EF-Ts).

Crystal Structure of Ribosome-Inactivating Protein Ricin A Chain in Complex with the C-Terminal Peptide of the Ribosomal Stalk Protein P2

open access: yesToxins, 2016
Ricin is a type 2 ribosome-inactivating protein (RIP), containing a catalytic A chain and a lectin-like B chain. It inhibits protein synthesis by depurinating the N-glycosidic bond at α-sarcin/ricin loop (SRL) of the 28S rRNA, which thereby prevents the ...
