Cyclic homodimer formation by singlet oxygen-mediated oxidation of carnosine

open access: yesFrontiers in Chemistry
Although carnosine (β-Ala-L-His) is one of physiological protectants against in vivo damages caused by reactive oxygen species (ROS), its reactivity against singlet oxygen (1O2), an ROS, is still unclear at the molecular level.

MSFragger: ultrafast and comprehensive peptide identification in shotgun proteomics

open access: yesNature Methods, 2017
There is a need to better understand and handle the 'dark matter' of proteomics—the vast diversity of post-translational and chemical modifications that are unaccounted in a typical mass spectrometry–based analysis and thus remain unidentified.

The dual nature of TDC – bridging dendritic and T cells in immunity

open access: yesFEBS Letters, EarlyView.
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Feedback Inhibition of CREB Signaling Promotes Beta Cell Dysfunction in Insulin Resistance

open access: yesCell Reports, 2015
Although persistent elevations in circulating glucose concentrations promote compensatory increases in pancreatic islet mass, unremitting insulin resistance causes deterioration in beta cell function that leads to the progression to diabetes.

Peptide Bioinformatics- Peptide Classification Using Peptide Machines [PDF]

open access: yes, 2008
Peptides scanned from whole protein sequences are the core information for many peptide bioinformatics research such as functional site prediction, protein structure identification, and protein function recognition. In these applications, we normally need to assign a peptide to one of the given categories using a computer model.

Preferred Configurations of Peptide–Peptide Interactions

open access: yesThe Journal of Physical Chemistry A, 2013
The natural and fundamental proclivities of interaction between a pair of peptide units are examined using high-level ab initio calculations. The NH···O H-bonded structure is found to be the most stable configuration of the N-methylacetamide (NMA) model dimer, but only slightly more so than a stacked arrangement.

A Comprehensive Review on Current Advances in Peptide Drug Development and Design

open access: yesInternational Journal of Molecular Sciences, 2019
Protein–protein interactions (PPIs) execute many fundamental cellular functions and have served as prime drug targets over the last two decades. Interfering intracellular PPIs with small molecules has been extremely difficult for larger or flat binding ...
