Our principal interest is to understand the fundamental aspect of protein synthesis mechanisms and regulations.

Looks super cool, can’t wait to try it
Collaborative work of @slavicaPD, @Hashemyaser4, Jovanovic Lab and @DjuranovicLab - a new method to isolate ribosomes and translational material in minutes. We show multiple usage of our RAPPL method in biochemical and structural assays with ribosomes. Please be free to contact us for further instructions if needed. @IsraelF96135088 you'll like this one.
A rapid, facile, and economical method for the isolation of ribosomes and translational machinery for structural and functional studies biorxiv.org/content/10.1101/…

Our timely contribution to the growing body of YebC2/TACO1 literature 🤩! YebC2 is a third factor that prevents ribosome stalling at prolines. Associates with 70S and important for fitness in absence of EF-P and YfmR.

This is really a stunning paper.
Cyanobacteria exposed to shorter days (in the lab) "rewire" their membrane lipids to anticipate cold weather.
When those cells are plunged into cold water, they have "two or three-times higher survival" than cells exposed to longer days.

Our collaboration with @WilsonLab2 and @vpelech is out in @NAR_Open! The ABCF ATPase New1 resolves translation termination defects associated with specific tRNAArg and tRNALys isoacceptors in the P site

Congrats to @biozentrum @snsf_ch Ambizione Group Leader @FlorentWaltz on this stunning study🤩 of respirasome structure & organization inside native cells! It's amazing how quickly in situ #cryoET is advancing. Read Florent's thread🧵 for the high-resolution details🔎🦠 #TeamTomo
Super excited to share our latest work on the native in-cell organization of the mitochondrial respiratory chain 🥳
Using cryo-electron tomography🔬, we show how the respiratory complexes (and other complexes) are organized inside native mitochondria!

Here, Koch lab reports on bacterial ribosome hibernation. They show that the membrane-tethering hibernation factors YqjD/ElaB/YgaM, discovered by Wada in E. coli, are widely conserved in proteobacteria and likely target the ribosomal peptide tunnel👍

We designed a motif that makes the expression of YFP strongly EttA-dependent. This motif demonstrates that EttA's activity is only evident when the motif is present within the first 30 amino acids of the encoded sequence.
EttA-dependent regulation can be reversed—induced in the absence of EttA and repressed in its presence—by the use of a leader peptide like MgtL.
EttA regulation allows E. coli to adapt to environmental changes by rerouting the TCA cycle via the glyoxylate shunt. Our study shows that this pathway, along with the tartronate-semialdehyde pathway, is crucial for adapting to salt stress.
EttA rescues ribosomes that pause when repeats of acidic residues are present in the first 30 amino acids of the encoding sequences. These acidic residues can induce ribosomal stalling as well as abortive synthesis.
In this manuscript, we demonstrate the physiological function of the ABCF protein EttA in regulating central metabolism genes expression by alleviating ribosomal pausing caused by poly-acidic residues.
Very happy to announce that our paper “Global regulation via modulation of ribosome pausing by the ABC-F protein EttA” has been published nature.com/articles/s41467-0…. Congratulation to all the lab members and especially the first authors @ousalemF

Out now in @PNASNews we used Tn-seq to identify genetic interactions with EF-P in B. subtilis. We found that 1) the ABCF YfmR (Uup) is required in absence of EF-P in some conditions
