Structures and proton-pumping strategies of mitochondrial respiratory enzymes [PDF]

open access: yes, 2001
Enzymes of the mitochondrial respiratory chain serve as proton pumps, using the energy made available from electron transfer reactions to transport protons across the inner mitochondrial membrane and create an electrochemical gradient used for the ...

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

open access: yesBMC 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 ...

Substrate specificity of thioredoxins and glutaredoxins – towards a functional classification

open access: yesHeliyon, 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 ...

The Structure and Biological Function of CREG

open access: yesFrontiers 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

open access: yesFrontiers 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
