Conformationally Restricted Glycopeptide Backbone Inhibits Gas-Phase H/D Scrambling between Glycan and Peptide Moieties
Code, C., Qiu, D., Solov'yov, I. A., Lee, J.-G., Shin, H.-C., Roland, C., … Jorgensen, T. J. D. (2023, October 26). JOURNAL OF THE AMERICAN CHEMICAL SOCIETY.
TL;DR:
The results show that complete scrambling precedes the glycosidic bond cleavage in normal glycopeptides derived from a glycoprotein; i.e., all labile hydrogens have undergone positional randomization prior to loss of the glycan.

Comparative Structural and Computational Analysis Supports Eighteen Cellulose Synthases in the Plant Cellulose Synthesis Complex
Scientific Reports, 6(1).
Contributors: B. Nixon *, K. Mansouri n, A. Singh n, J. Du *, J. Davis n, n, E. Slabaugh n, V. Vandavasi*
MeSH headings : Cellulose / biosynthesis; Cellulose / chemistry; Glucosyltransferases / chemistry; Models, Molecular; Plant Proteins / chemistry; Protein Domains; Protein Folding; Protein Structure, Quaternary
TL;DR:
Improved transmission electron microscopy images and image averages of the rosette-type CSC are obtained, revealing the frequent triangularity and average cross-sectional area in the plasma membrane of its individual lobes and multifaceted data support a rosettes CSC with 18 CESAs that mediates the synthesis of a fundamental microfibril composed of 18 glucan chains.

Structural determination of large molecules through the reassembly of optimized fragments
JOURNAL OF MOLECULAR GRAPHICS & MODELLING, 27(3), 364–375.
author keywords: Divide and conquer; Geometry optimization; Ab initio; FORM
MeSH headings : Alanine / chemistry; Algorithms; Alkanes / chemistry; Models, Molecular; Organic Chemicals / chemistry; Particle Size
TL;DR:
It is found that FORM can predict the structure of these molecules with an acceptable accuracy, all at a computational cost that is 2-11 times less than conventional quantum mechanical methods at the Hartree-Fock (HF), density functional theory (DFT) and MP2 level of accuracy.

Deprotonation of solvated formic acid: Car-Parrinello and metadynamics simulations
JOURNAL OF PHYSICAL CHEMISTRY B, 110(5), 2325–2331.
MeSH headings : Computational Biology; Computer Simulation; Formates / chemistry; Hydrogen / chemistry; Models, Molecular; Oxygen / chemistry; Protons; Solvents / chemistry; Thermodynamics; Time Factors
TL;DR:
The microscopics of deprotonation and reprotonation of formic acid reveal the key role played by nearby water molecules in catalyzing the reactions, and reveal barriers similar to that obtained with the constrained free-energy calculation.

TL;DR:
An extensive first principles investigation of the binding of vancomycin, avoparcin, teicoplanin, and ristocetin aglycons with dipetides with Dipetides, in liquid as well as gas phase finds the order of Gly and d-Ala binding is reversed in solution.

First principles investigation of vancomycin and teicoplanin binding to bacterial cell wall termini
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 126(27), 8384–8385.
MeSH headings : Alanine / analogs & derivatives; Alanine / metabolism; Anti-Bacterial Agents / metabolism; Anti-Bacterial Agents / pharmacology; Bacteria / drug effects; Bacteria / metabolism; Cell Wall / drug effects; Cell Wall / metabolism; Dipeptides / metabolism; Kinetics; Lactates / metabolism; Teicoplanin / metabolism; Teicoplanin / pharmacology; Thermodynamics; Vancomycin / metabolism; Vancomycin / pharmacology
TL;DR:
An extensive first principles investigation of the binding of vancomycin and teicoplanin with d-Ala-d-Lac (characteristic of VREs and non-VREs) was found to be stronger by about 3-5 kcal/mol and due primarily to the oxygen-oxygen lone-pair repulsion characteristic of the antibiotic/d-AlA-d.Lac complex.
