This year marks the 50th anniversary of the coiled?‐?coil triple helical structure of collagen, first proposed by Ramachandran's group from Madras. The structure is unique among the protein secondary structures in that it requires a very specific tripeptide sequence repeat, with glycine being mandatory at every third position and readily accommodates the imino acids proline/hydroxyproline, at the other two positions. The original structure was postulated to be stabilized by two interchain… 
Stability of the hydration layer of tropocollagen: A QM study
TLDR
These water binding places on the surface of the triple helix can provide explanation on how an almost liquid‐like hydration environment exists between the closely packed tropocollagens and thus contribute to the elasticity of collagen.
How stable is a collagen triple helix? An ab initio study on various collagen and β‐sheet forming sequences
TLDR
The present study proves that by using first principles methods for calculating stabilities of supramolecular complexes, such as collagen and β‐pleated sheets, one can obtain stability data in full agreement with experimental observations, which envisage the applicability of QM in molecular design.
Unravelling the Role of Hydroxyproline in Maintaining the Thermal Stability of the Collagen Triple Helix Structure Using Simulation.
TLDR
This study constructed a collagen model with typical triple helix structure and calculated the hydrogen bond energy between collagen alpha chains and found that thermal unfolding did not occur simultaneously along the entire molecule, but started in the regions with less Hyp content.

TLDR
The current understanding of the structure of the collagen triple helical domain (COL×3) is summarized and an overview of some of the new developments in collagen molecular engineering aiming to produce novel collagen-based materials with superior properties are given.
Review of computer-aided models for predicting collagen stability.
TLDR
This study assembled data on a large number of collagen-like peptides to build the first Markov chain model for predicting the stability of the collagen at different temperatures, simply by analyzing the amino acid sequence, and validated the model with accuracy between 82% and 92%.
Molecular dynamic simulation studies on the effect of one residue chain staggering on the structure and stability of heterotrimeric collagen-like peptides with interruption.
TLDR
This is the first report on the structural effect on the heterotrimeric models with G4G and G1G breaks present simultaneously in the constituent chains with difference in one residue chain staggering.
Sequence position and side chain length dependence of charge pair interactions in collagen triple helices.
TLDR
The effect of salt on triple helix stability is examined and it is observed that increased salt concentration reduces the thermal stability of heterotrimers by an average of 5 °C, but does not disrupt helix assembly.
Orchestration of Structural, Stereoelectronic, and Hydrogen-Bonding Effects in Stabilizing Triplexes from Engineered Chimeric Collagen Peptides (Pro(X)-Pro(Y)-Gly)6 Incorporating 4(R/S)-Aminoproline.
TLDR
A new class of collagen analogues-chimeric cationic collagens-wherein both X- and Y-sites in collagen triad are simultaneously substituted by a combination of 4(R/S)-(OH/NH2/NH3(+)/NHCHO)-prolyl units and triplex stabilities measured at different pHs and in EG:H2O are described.

The molecular structure of collagen is now accepted to be based on a triple-stranded coiled-coil, in which the three strands are held together predominantly by hydrogen bonds. Recent experimental
Crystal and molecular structure of a collagen-like peptide at 1.9 A resolution.
TLDR
The structure of a protein triple helix has been determined by x-ray crystallographic studies of a collagen-like peptide containing a single substitution of the consensus sequence, which adopts a triple-helical structure that confirms the basic features determined from fiber diffraction studies on collagen.

TLDR
The study presented here is the first application of conformational energy computations to a real sequence in the collagen molecule and it is shown that side-chain-backbone interactions contribute substantially to the stabilization of the triple-helical structure of collagen with a natural sequence.

TLDR
The proposed structure of collagen is in good agreement with the infra-red and X-ray data and also fits in broadly with the amino-acid composition and other properties of collagen.
Staggered molecular packing in crystals of a collagen-like peptide with a single charged pair.
TLDR
The EKG structure suggests a molecular mechanism for stabilization at neutral pH values, where both Glu and Lys are ionized, but suggest that this occurs because of the effects of ionization on the individual residues, rather than ion pair formation.
