Aided by the solving of the structures of human NMT1 with substrate-mimicking peptides, mapping of human and Arabidopsis myristoylomes defines a myristoylation recognition motif and over 1,000 myristoylated protein targets.
Selectivity of ligand-induced protein degradation and dimerization is conferred by plastic interprotein contacts. Computational protein–protein docking reveals the underlying interprotein contacts to inform the design of a BRD4 selective degrader.
Copper contributes to regulating zebrafish rest–activity cycles through the locus coeruleus system by modulating the biosynthesis of norepinephrine; brain copper deficiency leads to lower levels of both synaptic norepinephrine and daytime activity.
Potent pan-Atg8 or GABARAP-selective inhibitory peptides derived from giant neuronal ankyrin-B and -G effectively block autophagy in cell cultures and in C. elegans spatiotemporally.
Functional and structural characterization of PtmA2 reveals that it is an unusual non-adenylating acyl-CoA ligase and part of a system wherein the canonical acyl-CoA ligase reaction is separated into two half-reactions performed by distinct enzymes.
A bioinformatic strategy beginning with solute-binding proteins involved in sugar transport led to the functional annotation of four previously unknown catabolic pathways of the branched pentose d-apiose.
Although the conversion of (7S)-salutaridinol 7-O-acetate to thebaine can occur spontaneously, the identification of a thebaine synthase enzyme that catalyzes the reaction indicates how nature avoids the formation of labile hydroxylated byproducts.
Computational protein design, without subsequent directed evolution, rapidly provides a set of aspartase variants capable of biocatalytic asymmetric addition of ammonia to substituted acrylates, producing various enantiopure β-amino acids.
A genome-wide uracil profiling technology (termed “dU-seq”), based on selective labeling and biotin pull-down, reveals that uracil is enriched at the centromere of the human genome.
ABP profiling identifies uncharacterized S. aureus serine hydrolases, including the surface-localized FphB, which processes lipid ester substrates and is required for infection in vivo. An FphB inhibitor reduces in vivo bacterial load.
Combination of single-molecule tracking experiments and machine-learning approaches to monitor diffusional state transitions between ribosome-bound and free tRNAs allows codon resolution measurements of translation kinetics.
The GlycoSCORES method, which involves cell-free protein expression and substrate-site profiling of glycosyltransferase enzymes by SAMDI–MS, enables the identification of glycosylation tags for glycoengineering efforts.
A β-lactamase, a novel type of amidase, and the phenylacetic acid catabolon comprise a catabolic pathway, revealed by genomic and transcriptomic analysis, that enables multiple soil bacteria to use β-lactam antibiotics as a carbon source.
The monomeric near-infrared (NIR) fluorescent protein miRFP720 enables development of fully NIR Förster resonance energy transfer (FRET) biosensors compatible with CFP–YFP FRET biosensors and blue–green optogenetic tools without optical cross-talk.
Ancestral sequence inference, directed evolution, structural analysis, NMR, and molecular dynamics simulations illuminate how enantioselective activity arises during the evolutionary trajectory of chalcone isomerase from a noncatalytic ancestor.
Ancestral protein reconstruction, with structural and biochemical analysis, illustrates the evolution of a solute-binding protein to cyclohexadienyl dehydratase through incorporation of a catalytic residue and gradual reshaping of the binding site.
Use of a combined Tn-seq and machine-learning approach for predicting mechanisms and targets of antibiotic action in Staphylococcus aureus shows that the natural product lysocin E (LysE) binds Lipid II on the cell surface and damages the membrane.
A phage-derived peptide selectively binds to the Frizzled 7 CRD resulting in disruption of the dimer interface and impairing Wnt/β-catenin stem signaling in intestinal organoids.
