A Rapid and Efficient Building Block Approach for Click Cyclization of Peptoids
Frontiers in Chemistry, 2020 Cyclic peptide-peptoid hybrids possess improved stability and selectivity over linear peptides and are thus better drug candidates. However, their synthesis is far from trivial and is usually difficult to automate.

Protein O‐glycosylation in the Bacteroidota phylum
FEBS Open Bio, EarlyView.Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Ebola virus VP30 and nucleoprotein interactions modulate viral RNA synthesis [PDF]
, 2017 Ebola virus (EBOV) is an enveloped negative-sense RNA virus that causes sporadic outbreaks with high case fatality rates. Ebola viral protein 30 (eVP30) plays a critical role in EBOV transcription initiation at the nucleoprotein (eNP) gene, with ...

Catalytic RNA and synthesis of the peptide bond [PDF]
We are studying whether the L-19 IVS ribozyme from Tetrahymena thermophila can catalyze the formation of the peptide bond when it is supplied with synthetic aminoacyl oligonucleotides.

Synthesis, screening, and sequencing of cysteine-rich one-bead one-compound peptide libraries. [PDF]
, 2008 Cysteine-rich peptides are valued as tags for biarsenical fluorophores and as environmentally important reagents for binding toxic heavy metals. Due to the inherent difficulties created by cysteine, the power of one-bead one-compound (OBOC) libraries has

The role of circular RNAs in regulating cytokine signaling in cancer
FEBS Open Bio, EarlyView.Cytokines present in the tumor microenvironment fuel cancer development. Aberrant expression of circRNAs contributes to cancer progression. Cytokines are involved in regulating circRNA biogenesis. Furthermore, aberrantly expressed circRNAs regulate the expression of ligands, receptors, and downstream effectors involved in cytokine signaling to promote ...
