Protein disulfide isomerase (PDI) is an endoplasmic reticulum (ER)-localized multifunctional enzyme that can function as a disulfide oxidase, a reductase, an isomerase, and a chaperone. The domain organization of PDI is abb'xa'c, with two catalytic (CxxC) motifs and a KDEL ER retention motif. The members of the PDI family exhibit differences in tissue distribution, specificity, and intracellula...
Complete active space self-consistent field (CASSCF) followed by multi-reference singles+doubles CI (MRSDCI) which included up to 2.3 million configurations are made on eight electronic states of Pd:. All eight states of Pd; were found to exhibit only slight Jahn-Teller distortion from ideal equilateral triangular structures. The ground state of Pdf was found lo be 4Bz with near-equilateral tri...
BACKGROUND The Provisional Diagnostic Instrument (PDI-4) is a brief, adult self-report instrument for 4 common psychiatric diagnoses in primary care patients: major depressive episode (MDE), generalized anxiety disorder (GAD), attention deficit hyperactivity disorder (ADHD), and bipolar I disorder based on past or present mania. Our objective was to assess validity of the PDI-4 in a population ...
Protein disulfide isomerases are overwhelmingly multi-modular redox catalysts able to perform the formation, reduction or isomerisation of disulfide bonds. We present here the biochemical characterization of three different poplar PDI isoforms. PDI-A is characterized by a single catalytic Trx module, the so-called a domain, whereas PDI-L1a and PDI-M display an a-b-b'-a' and a°-a-b organisation ...
BACKGROUND The Psoriasis Disability Index (PDI) is a widely used instrument to measure the impact of psoriasis on patients. There has not been psychometric evaluation of the Chinese version of PDI. The aim of this study was to evaluate its reliability and validity among Chinese patients with psoriasis. METHODS A multi-center, cross-sectional study was conducted at 9 hospitals including patien...
We prepared a solution-processed film comprising a drop-casted mixture of melamine-diacetylene and perylene bis(dicarboximide) (PDI). We show that the diacetylene monomers adopt distinct crystalline organization in the presence of the PDI residues. Importantly, the drop-casted diacetylene/PDI film exhibits ultraviolet light-induced conductivity, ascribed to effective transport of charge carrier...
Green fluorescent protein (GFP) has been widely used in several molecular and cellular biology applications, since it is remarkably stable in vitro and in vivo. Interestingly, native GFP is resistant to the most common chemical denaturants; however, a low fluorescence signal has been observed after acid-induced denaturation. Furthermore, this acid-denatured GFP has been used as substrate in stu...
1. The activities of protein disulphide-isomerase (PDI) and thioredoxin in catalysing disulphide bond isomerization in a protein substrate were compared by using the standard assay, namely the re-activation of 'scrambled' RNAase. 2. The specific activity of PDI was 25-fold greater than that of thioredoxin. 3. The greater efficiency of PDI compared with thioredoxin is considered to be due more t...
abstract background: low back pain (lbp) is still a medical problem in 21 st century. having back pain and being disabled by it are not the same thing. it is common to come across with patients who have simple back pain but surprisingly totally disabled and vice versa. in clinical practice, it is important to have a proper evaluation of disability and making a clear distinction between pain a...
To generate a cytopathic effect, the catalytic A1 subunit of cholera toxin (CT) must be separated from the rest of the toxin. Protein disulfide isomerase (PDI) is thought to mediate CT disassembly by acting as a redox-driven chaperone that actively unfolds the CTA1 subunit. Here, we show that PDI itself unfolds upon contact with CTA1. The substrate-induced unfolding of PDI provides a novel mole...
