Biocatalysts for Peptide Geranylation With Linear and Cyclic Prenyl Groups

open access: yesAngewandte Chemie International Edition, EarlyView.
A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids.

Impact of Galactolipids and Phosphatidylcholine on the Stability of Microalgal Oil‐In‐Water Emulsions

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Microalgal oil is a sustainable source of omega‐3 polyunsaturated fatty acids. However, it is very sensitive to lipid oxidation, especially in emulsions. While the presence of phospholipids and galactolipids in microalgal oil can influence its oxidation, their impact in oil‐in‐water emulsion is not yet fully understood. This study investigates

Multifunctional PVC/PVA‐ZnO Nanocomposites: Bridging Dielectric Response and Antibacterial Activity for Active Packaging Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
PVC and PVA polymer blends are studied as a function of frequency at room temperature to find the composition that gives the AC conductivity. The blend that has 75% PVC and 25% PVA is chosen as the matrix. Then 10% ZnO nanoparticles are added for food packaging. The change, in conductivity is used as a sign of activity and food freshness. ABSTRACT This

Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment

open access: yesAdvanced Physics Research, EarlyView.
Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.
