Plastic Diets Drive Microbiome and Metabolic Reprogramming in Wax Moth Larvae (Achroia grisella)

open access: yesArchives of Insect Biochemistry and Physiology, Volume 122, Issue 3, July 2026.
Wax moth larvae (Achroia grisella) can consume LDPE and PLA, triggering polymer‐specific restructuring of the gut microbiome and host metabolism. LDPE feeding enriches Bacillus spp. and is associated with shifts in carbohydrate and amino‐acid pathways consistent with hydrocarbon processing, whereas PLA feeding enriches Enterococcus spp.

Reprogramming Promiscuous Nonribosomal Peptide Synthetases for Production of Specific Peptides

open access: yes, 2019
Pairs of docking domains (DDs) mediate the selective interations between adjacent nonribosomal peptide synthetases (NRPSs) to form defined protein–protein interactions resulting in defined peptide sequences.

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Structural Biology of Nonribosomal Peptide Synthetases [PDF]

open access: yes, 2016
The nonribosomal peptide synthetases are modular enzymes that catalyze synthesis of important peptide products from a variety of standard and non-proteinogenic amino acid substrates. Within a single module are multiple catalytic domains that are responsible for incorporation of a single residue. After the amino acid is activated and covalently attached

Enzymatic Prenylation of Proteins and Peptides: From Cysteine S‐Prenylation to Tryptophan‐Selective Biocatalysis

open access: yesChemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
This review highlights biocatalytic prenylation as a versatile strategy for tailoring the functional properties of peptides and proteins. By comparing branched isoprenoids with linear lipids, we illustrate how specific prenyl architectures modulate the behaviors of lipidated proteins within membrane environments.
