Bacterial Chaperone Domain Insertions Convert Human FKBP12 into an Excellent Protein-Folding Catalyst—A Structural and Functional Analysis

open access: yesMolecules
Many folding enzymes use separate domains for the binding of substrate proteins and for the catalysis of slow folding reactions such as prolyl isomerization. FKBP12 is a small prolyl isomerase without a chaperone domain.

Rescue of conformational dynamics in enzyme catalysis by directed evolution

open access: yesNature Communications, 2018
A key challenge in the field of protein design and evolution is to understand the mechanisms by which directed evolution is improving enzymes. Here the authors combine different biophysical methods and give mechanistic insights into how directed ...

Novel Spiroannulated 3-Benzofuranones. Synthesis and Inhibition of the Human Peptidyl Prolyl cis/trans Isomerase Pin1

open access: yesMolecules, 2008
The novel 3H-spiro[1-benzofuran-2-cyclopentan]-3-one skeleton has been madeaccessible by different routes. One- and two-step protocols lead to tricyclic and tetracyclicbenzofuranones 2 and 3, respectively.

The cis/trans interconversion of the calcium regulating hormone calcitonin is catalyzed by cyclophilin [PDF]

open access: yes, 1993
The cytosolic peptidyl-prolyl cis/trans isomerase cyclophilin from pig kidney can accelerate catalytically the cis/trans isomerization of prolyl peptide bonds.

FKBP10 Regulates Protein Translation to Sustain Lung Cancer Growth

open access: yesCell Reports, 2020
Summary: Cancer therapy is limited, in part, by lack of specificity. Thus, identifying molecules that are selectively expressed by, and relevant for, cancer cells is of paramount medical importance. Here, we show that peptidyl-prolyl-cis-trans-isomerase (

Structural and biochemical characterization of the human cyclophilin family of peptidyl-prolyl isomerases. [PDF]

open access: yesPLoS Biology, 2010
Peptidyl-prolyl isomerases catalyze the conversion between cis and trans isomers of proline. The cyclophilin family of peptidyl-prolyl isomerases is well known for being the target of the immunosuppressive drug cyclosporin, used to combat organ ...

Cyclophilin-A is bound to through its peptidylprolyl isomerase domain to the cytoplasmic dynein motor protein complex [PDF]

open access: yes, 2004
Although cyclophilin A (CyP-A) is a relatively abundant small immunophilin present in the cytoplasm of all mammalian cells, its general function(s) in the absence of the immunosuppressant drug cyclosporin A is not known.

Proteasomal Degradation of Human Peptidyl Prolyl Isomerase Pin1-pointing Phospho Bcl2 toward Dephosphorylation

open access: yesNeoplasia: An International Journal for Oncology Research, 2002
Microtubule inhibitor-induced Bcl2 phosphorylation is detrimental to its antiapoptotic function. Phosphorylation of Bcl2 predominantly occurs on two serine residues (70 and 87) in cells arrested at G2-M phase by microtubule disarraying agents.

Proline/arginine dipeptide repeat polymers derail protein folding in amyotrophic lateral sclerosis

open access: yesNature Communications, 2021
The most frequent cause of familial Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) are hexanucleotide repeat expansions in the non-coding region of the C9ORF72 gene that are translated into five dipeptide repeat (DPR) proteins ...

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 ...
