Deciphering the substrate recognition mechanisms of the heparan sulfate 3-O-sulfotransferase-3
Co-crystallization and biochemical analyses with structurally defined oligosaccharides show the low reactivity of HS 3-OST-3 toward 6-O-sulfated substrates is due to inhibition of enzyme activity by 6-O-sulfated oligosaccharides.
Metathramycin, a new bioactive aureolic acid discovered by heterologous expression of a metagenome derived biosynthetic pathway
Heterologous expression of an aromatic polyketide biosynthetic gene cluster recovered from a New Zealand soil metagenome library resulted in the discovery of new bioactive aureolic acids.
Hyaluronan (HA)-inspired glycopolymers as molecular tools for studying HA functions

A revision is proposed to the biosynthetic pathway to the well-known red pigment prodigiosin via a new thioester intermediate.
Site-specific modification and segmental isotope labelling of HMGN1 reveals long-range conformational perturbations caused by posttranslational modifications
Using protein semi-synthesis, segmentally isotope-labelled variants of nucleosome-binding protein HMGN1 were generated with site-specific posttranslational modifications to explore their structural and functional effects.
In vivo modulation of ubiquitin chains by N-methylated non-proteinogenic cyclic peptides
Cyclic peptides containing unnatural amino acids can modulate Lys-48 ubiquitin chains in cells and animals.
In silico peptide-directed ligand design complements experimental peptide-directed binding for protein–protein interaction modulator discovery
Using the protein–protein interaction of Mcl-1/Noxa, two methods for efficient modulator discovery are directly compared.
A peptidic inhibitor for PD-1 palmitoylation targets its expression and functions
We show for the first time that PD-1 is palmitoylated, identify DHHC9 as the predominant enzyme for its palmitoylation, and reveal the molecular mechanisms underlying its effects on PD-1 stability and functions. Importantly, we also designed PD1-PALM, a competitive inhibitor of PD-1 palmitoylation, and this first-in-class molecule may inspire the development of new checkpoint inhibitors.
