Structural modeling and functional analysis of the essential ribosomal processing protease Prp from Staphylococcus aureus [PDF]

open access: yes, 2017
In Firmicutes and related bacteria, ribosomal large subunit protein L27 is encoded with a conserved N-terminal extension that is removed to expose residues critical for ribosome function. Bacteria encoding L27 with this N-terminal extension also encode a

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Involvement of BcYak1 in the Regulation of Vegetative Differentiation and Adaptation to Oxidative Stress of Botrytis cinerea

open access: yesFrontiers in Microbiology, 2018
Yak1, a member of the dual-specificity tyrosine phosphorylation-regulated protein kinases, plays an important role in diverse cellular processes in fungi. However, to date, the role of BcYak1 in Botrytis cinerea, the causal agent of gray mold diseases in

Consensus mutagenesis reveals that non-helical regions influence thermal stability of horseradish peroxidase [PDF]

open access: yes, 2008
The enzyme horseradish peroxidase has many uses in biotechnology but a stabilized derivative would have even wider applicability. To enhance thermal stability, we applied consensus mutagenesis (used successfully with other proteins) to recombinant ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Identification of amino acid residues in the ligand binding repeats of LDL receptor important for PCSK9 binding[S]

open access: yesJournal of Lipid Research, 2019
Proprotein convertase subtilisin/kexin type 9 (PCSK9) promotes LDL receptor (LDLR) degradation, increasing plasma levels of LDL cholesterol and the risk of cardiovascular disease.

Site directed mutagenesis of L-pyrrolysine in dimethylamine methyltransferase [PDF]

open access: yes, 2009
Methanosarcina barkeri is an archaeon and is able to use methylamines as growth substrates for methanogenesis. The methylamine methyltransferases that are involved in initiating methanogenesis from the methylamines have an in-frame amber codon (UAG) that

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Broad Purpose Vector for Site-Directed Insertional Mutagenesis in Bifidobacterium breve

open access: yesFrontiers in Microbiology, 2021
Members of the genus Bifidobacterium are notoriously recalcitrant to genetic manipulation due to their extensive and variable repertoire of Restriction-Modification (R-M) systems.
