In silico optimization of a guava antimicrobial peptide enables combinatorial exploration for peptide design

2018
Nat Commun
PMCID: 5902452
PMID: 29662055
DOI: 10.1038/s41467-018-03746-3

[…] using the calibration by Hyberts et al.. The angle restraints of phi and psi of the protein backbone dihedral angles were predicted based on analysis of 1Hα and 13Cα chemical shifts using the program TALOS+. Several cycles of XPLOR were performed using standard protocols. After each cycle rejected restraints, side-chain assignments, NOEs, and dihedral violations were analyzed. Two hundred structur […]

[…] tained were 2.8, 3.4, and 5.0 Å (strong, medium, and weak NOE, respectively). Forty-four dihedral angle restrains were obtained from analysis of Cα, Hα, Cβ, N, and HN chemical shifts with the program TALOS+ (). Structure calculations were performed using the Xplor-NIH software, version 2.27 (). A total of 100 structures, starting with an extended conformation, were generated using a simulated anne […]

[…] ESY spectra (NOEs from the filtered NOESY experiment were defined as intermolecular while the NOEs in the other NOESY experiments were treated as ambiguous) and dihedral angle restraints estimated by TALOS+ (). Typical annealing parameters were used for distance (10, 15, 50 and 100 Kcal/mol for high temperature, initial cool1, final cool1 and cool2 force constants) and dihedral restraints (50, 150 […]

Solution structure and dynamics of anti CRISPR AcrIIA4, the Cas9 inhibitor

2018
Sci Rep
PMCID: 5832863
PMID: 29497118
DOI: 10.1038/s41598-018-22177-0

[…] raints were derived from the NOE spectra and classified into distance ranges according to the peak intensity. ϕ/ψ torsion angle restraints were derived from backbone chemical shifts using the program TALOS+. The solution structure of AcrIIA4 was calculated by simulated annealing in torsion angle space using the Xplor-NIH program. The target function of simulated annealing included a covalent geome […]

[…] to 0 °C. All experiments used 100 kHz of 1H decoupling using SPINAL-64 and 10 kHz of MAS spinning. Spectra were analyzed with CcpNmr Analysis 2.4.0. Secondary structure analysis was accomplished with TALOS+ based on the 13Cα, 13Cβ, 13C backbone carbonyl, and 15N backbone amide chemical shifts (Supplementary Table ). The analyzed fibrils were formed under conditions identical to our cryo-EM samples […]
