A New Colorimetric Assay for Methionyl Aminopeptidases: Examination of the Binding of a New Class of Pseudopeptide Analog Inhibitors [PDF]

open access: yes, 2006
A direct and convenient spectrophotometric assay has been developed for methionine aminopeptidases (MetAPs). The method employs the hydrolysis of a substrate that is a methionyl analogue of p-nitroaniline (l-Met-p-NA), which releases the chromogenic ...

Recent Progress on Giant Molecules: Synthesis, Assembly, and Applications

open access: yesChemistry–Methods, Volume 6, Issue 3, March 2026.
Giant molecules are molecules constructed by molecular nanoparticles with precise, rigid structure, have similar structures with small molecules and a large size as macromolecules. In this review, the constituent modules of giant molecules, as well as their synthesis, self‐assembly, applications in various fields and future developing prospect are ...

Aminopeptidases do not directly degrade tau protein

open access: yesMolecular Neurodegeneration, 2010
Background Tau hyperphosphorylation and aggregation to form intracellular neurofibrillar tangles is prevalent in a number of tauopathies. Thus there is current interest in the mechanisms involved in Tau clearance. It was recently reported that Tau can be

Characterization of the Active Site and Insight into the Binding Mode of the Anti-angiogenesis Agent Fumagillin to the Manganese(II)-Loaded Methionyl Aminopeptidase from \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

open access: yes, 2005
EPR spectra were recorded for methionine aminopeptidase from Escherichia coli (EcMetAP-I) samples (~2.5 mM) to which one and two equivalents of Mn(II) were added (the latter is referred to as [MnMn(EcMetAP-I)]).

Non‐cognate CD8 Binding to MHC I Promotes Positive Selection of an MHC‐E Restricted CD8 T Cell Population

open access: yesEuropean Journal of Immunology, Volume 56, Issue 3, March 2026.
Mouse Qa1b‐restricted T cells show promiscuous requirements for positive selection. Using in vivo tetramer enrichment, in vitro APC engineering, and in vitro thymocyte stimulation, we demonstrate that a Qa1b‐restricted T cell population can be selected by both Qa1b and H2‐T11, and depends on non‐cognate CD8‐MHC I binding.

Purification and partial characterization of Phaseolus vulgaris seed aminopeptidase

open access: yesBrazilian Journal of Medical and Biological Research, 1999
The aminopeptidase activity of Phaseolus vulgaris seeds was measured using L-Leu-p-nitroanilide and the L-aminoacyl-ß-naphthylamides of Leu, Ala, Arg and Met.

The Catalytic Role of Glutamate 151 in the Leucine Aminopeptidase from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e [PDF]

open access: yes, 2004
Glutamate 151 has been proposed to act as the general acid/base during the peptide hydrolysis reaction catalyzed by the co-catalytic metallohydrolase from Aeromonas proteolytica (AAP).

Development of Protacs to Target Cancer-promoting Proteins for Ubiquitination and Degradation [PDF]

open access: yes, 2003
The proteome contains hundreds of proteins that in theory could be excellent therapeutic targets for the treatment of human diseases. However, many of these proteins are from functional classes that have never been validated as viable candidates for the ...

Effects of Probiotic Supplementation on Symptoms and Microbiome Characteristics in Patients With Non‐Celiac Gluten/Wheat Sensitivity: A Randomized Controlled Double‐Blind Trial

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
This randomized, double‐blind, placebo‐controlled trial demonstrated that probiotic supplementation in individuals with non‐celiac gluten/wheat sensitivity improved tolerance to gluten reintroduction in nearly half of participants. The effect was associated with beneficial shifts in gut microbiome composition and function, including enhanced microbial ...
