Vibrational studies of the disulfide group in proteins. Part V. Correlation of SS stretch frequencies with the CCSS dihedral angle in known protein disulfide bridges.

چکیده
Normal mode calculations have been done on 92 disulfide bridges in 25 known protein structures in order to correlate the SS stretch frequency with the CCSS dihedral angle. It is possible to classify the frequencies into four major categories, which provide a more detailed classification scheme than previously proposed from dialkyl disulfide correlations.

Vibrational studies of the disulfide group in proteins. VI. General correlations of SS and CS stretch frequencies with disulfide bridge geometry.
Normal mode calculations have been done on a range of disulfide bridge conformations in order to determine how the SS stretch and CS stretch frequencies depend on structure. In addition to varying the C alpha C beta SS and NC alpha C beta S dihedral angles, we have varied the phi, psi of the adjoining peptide groups since we have shown that these also influence the above frequencies. In order t...
متن کاملMolecular Characterization of a Three-disulfide Bridges Beta-like Neurotoxin from Androctonus crassicauda Scorpion Venom
Scorpion venom is the richest source of peptide toxins with high levels of specific interactions with different ion-channel membrane proteins. The present study involved the amplification and sequencing of a 310-bp cDNA fragment encoding a beta-like neurotoxin active on sodium ion-channel from the venom glands of scorpion Androctonus crassicauda belonging to the Buthidae family using r...
متن کاملNMR structure of the Euplotes raikovi pheromone Er-23 and identification of its five disulfide bonds.
The NMR solution structure of the 51 residue pheromone Er-23 from the ciliated protozoan Euplotes raikovi (Er) was calculated with the torsion angle dynamics program DYANA from 582 nuclear Overhauser enhancement (NOE) upper limit distance constraints, 46 dihedral angle constraints and 30 disulfide bond constraints. The disulfide bridges had not been assigned by chemical methods, and initially w...
متن کاملRecombinant Production of a Novel Fusion Protein: Listeriolysin O Fragment Fused to S1 Subunit Of Pertussis Toxin
Background: Some resources have suggested that genetically inactivated pertussis toxoid (PTs) bear a more protective effect than chemically inactivated products. This study aimed to produce new version of PT, by cloning an inactive pertussis toxin S1 subunit (PTS1) in a fusion form with N-terminal half of the listeriolysin O (LLO) pore-forming toxin. Methods: Deposited pdb structure file of the...
متن کاملA Novel Vector for Expression/Secretion of Properly Folded Eukaryotic Proteins: a Comparative Study on Cytoplasmic and Periplasmic Expression of Human Epidermal Growth Factor in E. coli
Expression of eukaryotic proteins in E. coli often results in their aggregation. Proper folding and solubility of therapeutical proteins are the pre-requisite for their bioactivity. This is not achieved in cytoplasmic expression in E. coli because of the absence of disulfide bonds formation. A novel expression/secretion vector was constructed which exploited β-lactamase signal sequence to trans...
