Introduction to Peptidyl-Prolyl cis/trans Isomerase (PPIase) Series

open access: yesBiomolecules, 2019
About 30 years after the discovery of peptidyl-prolyl cis/trans isomerases (PPIases), research on this group of proteins has become somewhat calmer than it used to be, but it still generates lots of interest [...]

Molecular Chaperones in Cancer Stem Cells: Determinants of Stemness and Potential Targets for Antitumor Therapy

open access: yesCells, 2020
Cancer stem cells (CSCs) are a great challenge in the fight against cancer because these self-renewing tumorigenic cell fractions are thought to be responsible for metastasis dissemination and cases of tumor recurrence. In comparison with non-stem cancer

Three unrelated and unexpected amino acids determine the susceptibility of the interface cysteine to a sulfhydryl reagent in the triosephosphate isomerases of two trypanosomes. [PDF]

open access: yesPLoS ONE, 2018
Proteins with great sequence similarity usually have similar structure, function and other physicochemical properties. But in many cases, one or more of the physicochemical or functional characteristics differ, sometimes very considerably, among these ...

Mitochondrial Thioredoxin System as a Modulator of Cyclophilin D Redox State [PDF]

open access: yes, 2016
The mitochondrial thioredoxin system (NADPH, thioredoxin reductase, thioredoxin) is a major redox regulator. Here we have investigated the redox correlation between this system and the mitochondrial enzyme cyclophilin D.

A humanized monoclonal antibody that inhibits platelet-surface ERp72 reveals a role for ERp72 in thrombosis [PDF]

open access: yes, 2017
Background: Within the endoplasmic reticulum, thiol isomerase enzymes modulate the formation and rearrangement of disulphide bonds in newly folded proteins entering the secretory pathway to ensure correct protein folding.

The platelet-surface thiol isomerase enzyme ERp57 modulates platelet function [PDF]

open access: yes, 2011
Background: Thiol isomerases are a family of endoplasmic reticulum enzymes which orchestrate redox-based modifications of protein disulphide bonds. Previous studies have identified important roles for the thiol isomerases PDI and ERp5 in the regulation ...

Is EC class predictable from reaction mechanism?

open access: yesBMC Bioinformatics, 2012
Background We investigate the relationships between the EC (Enzyme Commission) class, the associated chemical reaction, and the reaction mechanism by building predictive models using Support Vector Machine (SVM), Random Forest (RF) and k-Nearest ...

Requirement of Peptidyl-Prolyl Cis/Trans isomerases and chaperones for cellular uptake of bacterial AB-type toxins

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Bacterial AB-type toxins are proteins released by the producing bacteria and are the causative agents for several severe diseases including cholera, whooping cough, diphtheria or enteric diseases.

A theoretical estimate for nucleotide sugar demand towards Chinese Hamster Ovary cellular glycosylation [PDF]

open access: yes, 2016
Glycosylation greatly influences the safety and efficacy of many of the highest-selling recombinant therapeutic proteins (rTPs). In order to define optimal cell culture feeding strategies that control rTP glycosylation, it is necessary to know how ...

A shape-shifting redox foldase contributes to Proteus mirabilis copper resistance

open access: yesNature Communications, 2017
Bacterial disulfide isomerases shuffle incorrect disulfide bonds. Here, the authors structurally characterize the disulfide isomerase ScsC fromProteus mirabilisand identify a functionally important shape-shifting motif that allows ScsC to adopt a diverse
