Folding of a single domain protein entering the endoplasmic reticulum precedes disulfide formation [PDF]

open access: yes, 2017
The relationship between protein synthesis, folding and disulfide formation within the endoplasmic reticulum (ER) is poorly understood. Previous studies have suggested pre-existing disulfide links are absolutely required to allow protein folding and ...

Disruption of reducing pathways is not essential for efficient disulfide bond formation in the cytoplasm of E. coli

open access: yesMicrobial Cell Factories, 2010
Background The formation of native disulfide bonds is a complex and essential post-translational modification for many proteins. The large scale production of these proteins can be difficult and depends on targeting the protein to a compartment in which ...

Multiple Disulfide-Bonded States of Native Proteins: Estimate of Number Using Probabilities of Disulfide Bond Formation

open access: yesMolecules, 2020
The polypeptide backbone of proteins is held together by two main types of covalent bonds: the peptide bonds that link the amino acid residues and the disulfide bonds that link pairs of cysteine amino acids. Disulfide bonds form as a protein folds in the

Review

open access: yes, 2020
The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...

Disulfide bond isomerization in prokaryotes

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2008
Proteins with multiple cysteine residues often require disulfide isomerization reactions before they attain their correct conformation. In prokaryotes this reaction is catalyzed mainly by DsbC, a protein that shares many similarities in structure and mechanism to the eukaryotic protein disulfide isomerase.

Elucidation of the disulfide folding pathway of hirudin by a topology-based approach [PDF]

open access: yes, 2003
A theoretical model for the folding of proteins containing disulfide bonds is introduced. The model exploits the knowledge of the native state to favour the progressive establishment of native interactions.

Electron Transport Chain Is Biochemically Linked to Pilus Assembly Required for Polymicrobial Interactions and Biofilm Formation in the Gram-Positive Actinobacterium Actinomyces oris. [PDF]

open access: yes, 2017
The Gram-positive actinobacteria Actinomyces spp. are key colonizers in the development of oral biofilms due to the inherent ability of Actinomyces to adhere to receptor polysaccharides on the surface of oral streptococci and host cells.

Single-molecule studies of disulfide bond reduction pathways used by human thioredoxin [PDF]

open access: yes, 2013
Disulfide bond reduction pathways used by human thioredoxin (hTrx) are studied at the single molecule level using a recombinant protein (I27[subscript SS])[subscript 8].

Oxidative protein biogenesis and redox regulation in the mitochondrial intermembrane space [PDF]

open access: yes, 2016
Mitochondria are organelles that play a central role in cellular metabolism, as they are responsible for processes such as iron/sulfur cluster biogenesis, respiration and apoptosis.

In Silico Analysis of Glucose Oxidase from Aspergillus niger: Potential Cysteine Mutation Sites for Enhancing Protein Stability

open access: yesBioengineering, 2021
Glucose oxidase (GOx) holds considerable advantages for various applications. Nevertheless, the thermal instability of the enzyme remains a grand challenge, impeding the success in applications outside the well-controlled laboratories, particularly in ...
