Protein disulfide-isomerase - Wikipedia
Protein disulfide isomerase (EC 5.3.4.1), or PDI, is an enzyme in the endoplasmic reticulum (ER) in eukaryotes and the periplasm of bacteria that catalyzes the formation and breakage of disulfide bonds between cysteine residues within proteins as they fold.
The human protein disulfide isomerase gene family
2012年7月5日 · Enzyme-mediated disulfide bond formation is a highly conserved process affecting over one-third of all eukaryotic proteins. The enzymes primarily responsible for facilitating thiol-disulfide exchange are members of an expanding family of proteins known as protein disulfide isomerases (PDIs).
The Protein Disulfide Isomerase Family: from proteostasis to ...
2020年2月1日 · Oxidative folding and chaperoning in the ER are assisted by ~20 PDI family members. PDIs recognize and act on clients via conserved interdomain flexibility. Exactly how PDIs maintain protein homeostasis remains to be uncovered.
Functions and mechanisms of protein disulfide isomerase family …
Herein, we review recent research advances on PDIs, vis-à-vis their expression, functions, and molecular mechanisms in supporting cancer growth with special emphasis on the anterior gradient (AGR) subfamily. Last, we posit the relevance and therapeutic strategies in …
A structural overview of the PDI family of proteins
2010年8月26日 · Analysis of the structures reveals common features shared by several of the best known PDI family members, and also unique features related to substrate and partner binding sites. These exciting breakthroughs provide a deeper understanding of the mechanisms of oxidative protein folding in cells.
The human protein disulfide isomerase gene family - PMC
Enzyme-mediated disulfide bond formation is a highly conserved process affecting over one-third of all eukaryotic proteins. The enzymes primarily responsible for facilitating thiol-disulfide exchange are members of an expanding family of proteins …
The human PDI family: Versatility packed into a single fold
2008年4月1日 · The enzymes of the protein disulfide isomerase (PDI) family are thiol–disulfide oxidoreductases of the endoplasmic reticulum (ER). They contain a CXXC active-site sequence where the two cysteines catalyze the exchange of a disulfide bond with or within substrates.
The human protein disulphide isomerase family: substrate …
This review discusses recent advances in our understanding of the human PDI family of enzymes and focuses on their functional properties, substrate interactions and some recently identified family members.
The protein disulfide isomerase family: key players in health …
2012年4月15日 · In this review, the importance of PDI in health and disease will be examined, using examples from the fields of lipid homeostasis, hemostasis, infectious disease, cancer, neurodegeneration, and infertility.
The Protein Disulfide Isomerase Family: from proteostasis to ...
In mammalian cells, nearly one-third of proteins are inserted into the endoplasmic reticulum (ER), where they undergo oxidative folding and chaperoning assisted by approximately 20 members of the protein disulfide isomerase family (PDIs).
