Pom1 gradient buffering through intermolecular auto‐phosphorylation

Molecular Systems Biology, 2015
Concentration gradients provide spatial information for tissue patterning and cell organization, and their robustness under natural fluctuations is an evolutionary advantage.

Positional scanning and computational modeling reveal determinants of legumain transpeptidase activity

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Legumain is a lysosomal cysteine protease that plays a central role in antigen processing for MHC class II presentation. Beyond its canonical proteolytic activity, legumain can also function as a peptide ligase or transpeptidase. This non‐canonical activity becomes particularly relevant under pathophysiological conditions such as cancer and ...

Structure and Mechanism of PhdC, a Prenylated‐Flavin Maturase

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1019-1029, May 2026.
ABSTRACT Prenylated flavin mononucleotide (prFMN) is a modified flavin cofactor required by the UbiD family of (de)carboxylase enzymes. While the reduced prFMNH2 form is produced by the flavin prenyltransferase UbiX, the corresponding two‐electron oxidized prFMNiminium form is required to support UbiD catalysis. Thus, oxidative maturation of prFMNH2 is

Bromine Enrichment Signal in Svalbard Shallow Cores Reflects Changes of Seasonal Sea Ice Variability

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bromine enrichment Brenr $\left(\mathrm{B}{\mathrm{r}}_{\mathrm{e}\mathrm{n}\mathrm{r}}\right)$ has been widely used as a proxy for past sea ice reconstructions. In this study, three firn cores drilled on Holtedahlfonna (Svalbard) were analyzed for trace elements. Excluding a single year data, a positive correlation was observed between Brenr $

3D‐Printed Geopolymer as a Basic Heterogeneous Catalyst for the Synthesis of α‐Cyanoacrylates Through the Knoevenagel Condensation

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.
