Substrate specificity of thioredoxins and glutaredoxins – towards a functional classification

Heliyon, 2019
The spatio-temporal reduction and oxidation of protein thiols is an essential mechanism in signal transduction in all kingdoms of life. Thioredoxin (Trx) family proteins efficiently catalyze thiol-disulfide exchange reactions and the proteins are widely ...

Reductive enzymatic dynamic kinetic resolution affording 115 g/L (S)-2-phenylpropanol

BMC Biotechnology, 2021
Background Published biocatalytic routes for accessing enantiopure 2-phenylpropanol using oxidoreductases afforded maximal product titers of only 80 mM. Enzyme deactivation was identified as the major limitation and was attributed to adduct formation of ...

The Structure and Biological Function of CREG

Frontiers in Cell and Developmental Biology, 2018
The cellular repressor of E1A-stimulated genes (CREG) is a 220 amino acid glycoprotein structurally similar to oxidoreductases. However, CREG does not have enzymatic activities because it cannot bind to the cofactor flavin mononucleotide.

Diversity of D-Amino Acid Utilizing Bacteria From Kongsfjorden, Arctic and the Metabolic Pathways for Seven D-Amino Acids

Frontiers in Microbiology, 2020
D-amino acids (DAAs) are an important component of the refractory dissolved organic matter pool in the ocean. Microbes play a vital role in promoting the recycling of DAAs in the ocean. However, the diversity of marine DAA-utilizing bacteria and how they

The Effect of Two Amino acid Residue Substitutions via RNA Editing on Dark-operative Protochlorophyllide Oxidoreductase in the Black Pine Chloroplasts [PDF]

Scientific Reports, 2017
AbstractDark-operative protochlorophyllide oxidoreductase (DPOR) is a key enzyme to produce chlorophyll in the dark. Among photosynthetic eukaryotes, all three subunits chlL, chlN, and chlB are encoded by plastid genomes. In some gymnosperms, two codons of chlB mRNA are changed by RNA editing to codons encoding evolutionarily conserved amino acid ...

Trends in selenium utilization in marine microbial world revealed through the analysis of the global ocean sampling (GOS) project. [PDF]

PLoS Genetics, 2008
Selenium is an important trace element that occurs in proteins in the form of selenocysteine (Sec) and in tRNAs in the form of selenouridine. Recent large-scale metagenomics projects provide an opportunity for understanding global trends in trace element

Transcriptome sequencing leads to an improved understanding of the infection mechanism of Alternaria solani in potato

BMC Plant Biology, 2023
Background Alternaria solani (A. solani), the main pathogen of potato early blight, causes serious yield reductions every year. The application of fungicides is the most common and effective method of controlling Alternaria-caused diseases.

Molecular cloning and functional analysis of the thioredoxin gene SikTrxh from Saussurea involucrata

Biologia Plantarum, 2021
Thioredoxins are oxidoreductases that help to maintain redox homeostasis in plants under abiotic stress. In this study, a new thioredoxin gene, SikTrxh, was cloned from Saussurea involucrata (Kar.
