The High-Resolution Structures of the Neutral and the Low pH Crystals of Aminopeptidase from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e [PDF]

open access: yes, 2006
The aminopeptidase from Aeromonas proteolytica (AAP) contains two zinc ions in the active site and catalyzes the degradation of peptides. Herein we report the crystal structures of AAP at 0.95-Å resolution at neutral pH and at 1.24-Å resolution at low pH.

Scalable Engineering of Bio‐Manufactured Extracellular Vesicles for Selective Delivery in Ovarian Cancer Patient‐Derived Models

open access: yesAdvanced Science, EarlyView.
Engineered extracellular vesicles displaying Ephrin‐B2 selectively target Ephrin‐B4–expressing ovarian cancer cells, enabling precise delivery in patient‐derived models. This scalable bio‐manufacturing platform reveals a versatile strategy to exploit Ephrin signaling for highly specific therapeutic payload delivery and motivates exploration of tailored

Collagen processing and cuticle formation is catalysed by the astacin metalloprotease DPY-31 in free-living and parasitic nematodes [PDF]

open access: yes, 2010
The exoskeleton or cuticle performs many key roles in the development and survival of all nematodes. This structure is predominantly collagenous in nature and requires numerous enzymes to properly fold, modify, process and cross-link these essential ...

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

open access: yesAdvanced Science, EarlyView.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

Network development in biological gels: role in lymphatic vessel development [PDF]

open access: yes, 2008
In this paper, we present a model that explains the prepatterning of lymphatic vessel morphology in collagen gels. This model is derived using the theory of two phase rubber material due to Flory and coworkers and it consists of two coupled fourth order ...

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity

The PDZ domain of the SpoIVB serine peptidase facilitates multiple functions [PDF]

open access: yes, 2001
During spore formation in Bacillus subtilis, the SpoIVB protein is a critical component of the sigma (K) regulatory checkpoint. SpoIVB has been shown to be a serine peptidase that is synthesized in the spore chamber and which self-cleaves, releasing ...

Divalent Metal Binding Properties of the Methionyl Aminopeptidase from \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

open access: yes, 2000
The metal-binding properties of the methionyl aminopeptidase from Escherichia coli (MetAP) were investigated. Measurements of catalytic activity as a function of added Co(II) and Fe(II) revealed that maximal enzymatic activity is observed after the ...

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]

open access: yes, 2018
Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...
