Interconversion of (S)-glutamate and (2S,3S)-3-methylaspartate: A distinctive B-12-dependent carbon-skeleton rearrangement

open access: yes
The interconversion of (S)-glutamate and (2S,3S)-3-methylaspartate catalyzed by B-12-dependent glutamate mutase is discussed using results from high-level ab initio molecular orbital calculations.

Kainate, N-methylaspartate and other excitatory amino acids increase calcium influx into rat brain cortex cells in vitro

open access: yesNeuroscience Letters, 1983
Kainate (0.62-5 mM) was found to increase the initial rate of influx of 45Ca and of 22Na into the non-inulin space of rat thin brain cortex slices incubated in vitro, and to shorten the equilibration time for both these ions. N-methyl-DL-aspartate (50-1000 microM), L-glutamate (0.62-5 mM), DL-homocysteate (0.62-2.5 mM), and ibotenate (6-170 microM ...

Research Progress Based on SpyTag/SpyCatcher Self‐Assembling Peptides and Their Applications in the Food Field

open access: yesFood Bioengineering, Volume 4, Issue 3, Page 279-291, September 2025.
The formation of isopeptide bonds in the SpyTag/SpyCatcher system and its application in the food field ABSTRACT The SpyTag/SpyCatcher system is a modular protein assembly tool based on isopeptide bond‐mediated covalent conjugation, distinguished by mild reaction conditions, rapid ligation rate, and independence from exogenous enzymes or chemical ...

TxtH is a key component of the thaxtomin biosynthetic machinery in the potato common scab pathogen Streptomyces scabies

open access: yesMolecular Plant Pathology, Volume 20, Issue 10, Page 1379-1393, October 2019., 2019
Summary Streptomyces scabies causes potato common scab disease, which reduces the quality and market value of affected tubers. The predominant pathogenicity determinant produced by S. scabies is the thaxtomin A phytotoxin, which is essential for common scab disease development.

Amantadine Attenuates Secondary Oxidative and Inflammatory Injury by Modulating the HIF-1α/BNIP3L/HMGB1 Axis in Rat Model of Traumatic Brain Injury

open access: yesMedicina
Background and Objectives: Traumatic brain injury (TBI) triggers oxidative stress, mitochondrial dysfunction, and sterile inflammation. Amantadine (ATD), a weak NMDA receptor antagonist, has shown neuroprotective potential, but its mechanistic basis ...

Rex in Caldicellulosiruptor bescii: Novel regulon members and its effect on the production of ethanol and overflow metabolites

open access: yesMicrobiologyOpen, Volume 8, Issue 2, February 2019., 2019
Characterization of the Caldicellulosiruptor bescii Rex regulon using genetics, bioinformatics, RNA‐seq, metabolomics and fermentation. We identify novel regulon members and show a rex deletion strain can produce 54% more ethanol than the parent strain.

Quantitative chemical biosensing by bacterial chemotaxis in microfluidic chips

open access: yesEnvironmental Microbiology, Volume 20, Issue 1, Page 241-258, January 2018., 2018
Summary Whole‐cell bacterial bioreporters are proposed as alternatives to chemical analysis of, for example, pollutants in environmental compartments. Commonly based on reporter gene induction, bioreporters produce a detectable signal within 30 min to a few hours after exposure to the chemical target, which is impractical for applications aiming at a ...

A methylaspartate cycle in haloarchaea

open access: yes, 2011
Access to novel ecological niches often requires adaptation of metabolic pathways to cope with new environments. For conversion to cellular building blocks, many substrates enter central carbon metabolism via acetyl-coenzyme A (acetyl-CoA).
