Deletion of the Carboxyl-Terminal Residue Disrupts the Amino-Terminal Folding, Self-Association and Thermal Stability of an Amphipathic Antimicrobial Peptide

Wed, 24 Mar 2021 04:13:23 GMT

title: Deletion of the Carboxyl-Terminal Residue Disrupts the Amino-Terminal Folding, Self-Association and Thermal Stability of an Amphipathic Antimicrobial Peptide abstract: Understanding the complex relationship between amino acid sequence and protein behaviors, such as folding and self-association, is a major goal of protein research. In the present work, we examined the effects of deleting a C-terminal residue on the intrinsic properties of an amphapathic α-helix of mastoparan-B (MP-B), an antimicrobial peptide with the sequence LKLKSIVSWAKKVL-NH2. We used circular dichroism and nuclear magnetic resonance to demonstrate that the peptide MP-B([1-13]) displayed significant unwinding at the N-terminal helix compared with the parent peptide of MP-B, as the temperature increased when the residue at position 14 was deleted. Pulsed-field gradient nuclear magnetic resonance data revealed that MP-B forms a larger diffusion unit than MP-B([1-13]) at all experimental temperatures and continuously dissociates as the temperature increases. In contrast, the size of the diffusion unit of MP-B([1-13]) is almost independent of temperature. These findings suggest that deleting the flexible, hydrophobic amino acid from the C-terminus of MP-B is sufficient to change the intrinsic helical thermal stability and self-association. This effect is most likely because of the modulation of enthalpic interactions and conformational freedom that are specified by this residue. Our results implicate terminal residues in the biological function of an antimicrobial peptide.

Quantum wavefunctions representation with python language

Thu, 09 Apr 2020 04:10:49 GMT

title: Quantum wavefunctions representation with python language abstract: The Particle in a box (PIAB) is the most representative model to be used and illustrated for exactly solving the Schrodinger equation in quantum physics. However, as the degrees of freedom of this PIAB model from one dimensional case to three dimensional case the solutions of its wavefunction will become more difficult to visualize and comprehend. Therefore, in this research work we employed the most popular python programming language with its diverse workable modules and its diverse visualizing modules to easily obtain the visualizing representation, that is, isosurface, of solvable wavefunction of PIAB model in three dimensional case. Furthermore, this isosurface of wavefunction enables us to explore its interesting properties of wavefunction based on their different nx, ny and nz quantum numbers. Consequently, we are able to gain a very deep insight into this complex wavefunction of PIAB model in three dimensional case.

Reaction dynamics study for C-Br bond breaking within BrH2C-C-=C(ads) adsorbed on Ag(111) surface: Ab initio molecular dynamics approach

Tue, 15 Oct 2019 04:11:41 GMT

title: Reaction dynamics study for C-Br bond breaking within BrH2C-C-=C(ads) adsorbed on Ag(111) surface: Ab initio molecular dynamics approach abstract: The reaction dynamics for C–Br bond breaking within BrH2C–CºCH(ads) adsorbed on Ag(111) surface has been investigated by combining density functional theory-based molecular dynamics (DFTMD) simulations with short-time Fourier transform (STFT) analysis of the dipole moment autocorrelation function. Firstly, the initial perpendicular orientation of adsorbed BrH2C–CºCH(ads) with a stronger C–Br bond will undergo dynamic rotation leading to the final parallel orientation of BrH2C–CºCH(ads) to cause the C–Br bond breaking, namely, an indirect dissociation pathway. Secondly, the initial parallel orientation of adsorbed BrH2C–CºC(ads) with a weaker C–Br bond will directly cause the C–Br scission within BrH2C–CºCH(ads), namely, a direct dissociation. To further investigate the evolution of different vibrational modes of BrH2C–CºCH(ads) along these two reaction pathways, the STFT analysis is performed to illustrate that the infrared (IR) active peaks of BrH2C–CºCH(ads) such as vCH2 [2956 cm-1(s) and 3020 cm-1(as)], vºCH (3320 cm-1) and vCºC (2150 cm-1) gradually vanish as the rupture of C–Br bond occurs and then the resulting IR active peaks such as C=C=C (1812 cm-1), w-CH2 (780 cm-1) and d-CH (894 cm-1) appear due to the formation of H2C=C=CH(ads) which are in a good agreement with experimental reflection adsorption infrared spectrum (RAIRS) at temperatures of 110 and 200 K, respectively.

Self-Assembling of Peptides is Tuned via an Extended Amphipathic Helix

Sat, 11 May 2019 04:11:34 GMT

title: Self-Assembling of Peptides is Tuned via an Extended Amphipathic Helix abstract: Four peptides, C1 (spanning the helical segment of human neuropeptide Y from residue 15 to residue 29), C2 (spanning the helical segment of 21 to 31), C3 (the C-terminal fragment of neuropeptide Y involving residues 20 to 36) and P34-C3 (replacement of the glutamine with proline in position 34 of C3) were synthesized to study interaction between species. The information about the intermolecular interactions was extracted from their self-assembly behaviors. The results from CD and NMR showed that the addition of 2, 2, 2-trifluoroethanol (TFE) induces a stable amphipathic helix in each peptides and an extended helix was formed at the N-terminal of C1 and the C-terminal of C3. Pulsed field gradient NMR data revealed that C3 may undergo an enhanced interaction with TFE and a more favorable self-assembly as temperature was increased. In contrast, other three peptides were found to form larger size of oligomers at lower temperature and continuously dissociate into the monomeric form with increased temperature. Our results demonstrate that the self-assembly behavior may be tuned by the entropy and the energetics contributed by an extended helical conformation at terminus.
