Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

open access: yesFEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

The Structure and Function of Replication Protein A in DNA Replication

2012
In all organisms from bacteria and archaea to eukarya, single-stranded DNA binding proteins play an essential role in most, if not all, nuclear metabolism involving single-stranded DNA (ssDNA). Replication protein A (RPA), the major eukaryotic ssDNA binding protein, has two important roles in DNA metabolism: (1) in binding ssDNA to protect it and to ...

The Mechanism of Adenovirus DNA Replication and the Characterization of Replication Proteins

1983
The replication of the genome of human adenoviruses in permissive host cells is a highly efficient process. During the infection cycle a total amount of viral DNA is synthesized comparable to the entire chromosomal DNA content of the infected cell. In order to unravel the mechanism of adenovirus DNA replication this process has been studied in a number

MCM proteins and DNA replication

Current Opinion in Cell Biology, 2006
The MCM proteins identify a group of ten conserved factors functioning in the replication of the genomes of archae and eukaryotic organisms. Among these, MCM2-7 proteins are related to each other and form a family of DNA helicases implicated at the initiation step of DNA synthesis.

DNA replication in Escherichia coli: Replication in absence of protein synthesis after replication inhibition

Journal of Molecular Biology, 1970
Abstract In Escherichia coli, DNA replication can occur in the absence of protein synthesis after a period of replication inhibition. Such replication will occur after thymine starvation, nalidixic acid treatment or exposure of a DNA temperature-sensitive mutant to a period at the non-permissive temperature.
