Systemic application of bone-targeting peptidoglycan hydrolases as a novel treatment approach for staphylococcal bone infection

mBio, 2023
The current standard of treatment for chronic staphylococcal osteomyelitis entails high doses of antibiotics over the course of several weeks.

Soluble epoxide hydrolase limits mechanical hyperalgesia during inflammation [PDF]

, 2011
Background Cytochrome-P450 (CYP450) epoxygenases metabolise arachidonic acid (AA) into four different biologically active epoxyeicosatrienoic acid (EET) regioisomers.

In Vitro Stability and Inactivation of Peptide Hydrolases Extracted from Phaseolus vulgaris L. [PDF]

, 1981
Endopeptidase activity against azocasein had a higher temperature optimum (50°C) in leaf extracts than in cotyledon extracts (37°C). The temperature optima for aminopeptidase (46°C) and for carboxypeptidase (53°C) were similar in leaf and cotyledon ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Design of a Novel Peptide with Esterolytic Activity toward PET by Mimicking the Catalytic Motif of Serine Hydrolases [PDF]

Serine hydrolases have become increasingly important for recycling PET plastics. However, their properties are inherently constrained by their 3D structure, which in turn limits the conditions for their application.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Thermal Unfolding of Nucleoside Hydrolases from the Hyperthermophilic Archaeon Sulfolobus solfataricus: Role of Disulfide Bonds [PDF]

, 2012
Nucleoside hydrolases are metalloproteins that hydrolyze the N-glycosidic bond of β-ribonucleosides, forming the free purine/pyrimidine base and ribose.
