Double mimicry evades tRNA synthetase editing by toxic vegetable-sourced non-proteinogenic amino acid [PDF]

open access: yesNature Communications, 2017
Non-proteinogenic (np) amino acids in the food chain present challenges for the human translation machinery. Here the authors show that, while AlaRS and ProRS activate toxic np azetidine-2-carboxylic acid (Aze) present in sugar beets and lilies, only the

Leucyl-tRNA synthetase: double duty in amino acid sensing [PDF]

open access: yesCell Research, 2012
The cellular response to amino acids is controlled at the molecular level by TORC1. While many of the elements that participate in TORC1 signaling are known, we still have no clear idea how cells sense amino acids. Two recent studies found that leucyl-tRNA synthetase (LRS) is a leucine sensor for TORC1, in both yeast and mammalian cells.

Structural, Thermal and Surface Properties of a Formulated Sunscreen: Zn/Al-nitrate Layered Double Hydroxide Intercalated with 4-aminobenzoic Acid

open access: yesWalailak Journal of Science and Technology, 2021
Intercalation of 4-amino benzoic acid (4-AB) into Zn/Al-nitrate layered double hydroxide (ZAL2) to form Zn/Al-4AB (ZALAB) compound was successfully synthesized from nitrate salt by using direct co-precipitation method.

Impacts of Different Long-Term Fertilizer Management Regimes on Soil Nitrogen Mineralization and Its Enzyme Activities under a Double-Cropping Rice System in Southern China

open access: yesAgronomy, 2023
Soil extracellular enzyme activities play an important role in regulating the soil nitrogen (N) mineralization process in paddy fields. However, there is still a need to further study how N mineralization responds to different fertilizer management ...

Mass Spectrometry Guided Discovery and Design of Novel Asperphenamate Analogs From Penicillium astrolabium Reveals an Extraordinary NRPS Flexibility

open access: yesFrontiers in Microbiology, 2021
Asperphenamate is a small peptide natural product that has gained much interest due to its antitumor activity. In the recent years numerous bioactive synthetic asperphenamate analogs have been reported, whereas only a handful of natural analogs either of

A Healthy and Ecologically Balanced Environment: An Argument for a Third Generation Right [PDF]

open access: yes, 1993
Chymotrypsin-like serine proteases are found in high abundance in mast cell granules. By site-directed mutatgenesis, we have previously shown that basic amino acids in positions 143 and 192 (Arg and Lys respectively) of the human mast cell chymase are ...

Facile and Scalable Route to Access Rare Deoxy Amino Sugars for Nonulosonic Acid Aldolase Biosynthesis

open access: yesFrontiers in Chemistry, 2022
We presented a facile and scalable route for the synthesis of di-azido sugars via one-pot double inversion of the mono-benzoyl sugars by TBAN3 and studied the dependency pattern between solvent and protecting groups as well as the configuration of the ...

l-Amino Acid Production by a Immobilized Double-Racemase Hydantoinase Process: Improvement and Comparison with a Free Protein System [PDF]

open access: yes, 2017
Protein immobilization is proving to be an environmentally friendly strategy for manufacturing biochemicals at high yields and low production costs. This work describes the optimization of the so-called “double-racemase hydantoinase process,” a system of
