Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Gene sequences encoding ribosome-inactivating proteins from soapwort (Saponaria officinalis L.) [PDF]

, 1991
Ribosome-inactivating proteins (RIPs) are found in a wide variety of plant species. They possess an RNA N-glycosidase activity whereby the removal of a specific adenine residue from 28 S RNA renders a eukaryotic ribosome inactive.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

FEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Saporins - Type 1 Ribosome-inactivating proteins from soapwort (saponaria officinalis L.) [PDF]

, 1995
Ribosome-inactivating proteins (RlPs) are found distributed throughout the plant kingdom. These proteins possess a RNA N-glycosidase activity whereby the depurination of a specific adenine residue from the large ribosomal subunit renders eukaryotic and ...

The crystal structure of Nep1 reveals an extended SPOUT-class methyltransferase fold and a pre-organized SAM-binding site [PDF]

, 2008
Ribosome biogenesis in eukaryotes requires the participation of a large number of ribosome assembly factors. The highly conserved eukaryotic nucleolar protein Nep1 has an essential but unknown function in 18S rRNA processing and ribosome biogenesis.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Molecular Dynamics Simulations Suggest a Non-Doublet Decoding Model of −1 Frameshifting by tRNA^Ser3

Biomolecules, 2019
In-frame decoding in the ribosome occurs through canonical or wobble Watson−Crick pairing of three mRNA codon bases (a triplet) with a triplet of anticodon bases in tRNA.

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Aging in Rats Differentially Affects Markers of Transcriptional and Translational Capacity in Soleus and Plantaris Muscle

Frontiers in Physiology, 2017
Alterations in transcriptional and translational mechanisms occur during skeletal muscle aging and such changes may contribute to age-related atrophy. Herein, we examined markers related to global transcriptional output (i.e., myonuclear number, total ...

Ribosomal protein paralogues in ribosome specialization

Philosophical Transactions of the Royal Society B: Biological Sciences
Ribosomes are macromolecular complexes responsible for protein synthesis, comprising ribosomal proteins (RPs) and ribosomal RNA. While most RPs are present as single copies in higher eukaryotes, a handful of them have paralogues that emerged through duplication events.
