DOI: 10.1002/pro.4650
Abstract: (2R)‐4‐thiaproline (Thp) is an analog of proline, replacing Cγ in the pyrrolidine ring with sulfur. Its thiazolidine ring easily interconverts between endo and exo puckers due to a small energy barrier, which leads to destabilize… read more here.

DOI: 10.1016/j.cplett.2018.10.073
Abstract: Abstract As one of non-covalent forces to stabilize protein, cation-π interactions in collagen have been received much attention. Three chains of collagen form its characteristic secondary structure, triple helices. Based on a collagen heterotrimer, abc,… read more here.

DOI: 10.1021/acs.biochem.4c00334
Abstract: There are surprisingly few RNA intramolecular triple helices known in the human transcriptome. The structure has been most well-studied as a stability-element at the 3' end of lncRNAs such as MALAT1 and NEAT1, but the… read more here.

DOI: 10.1021/acs.biomac.0c00878
Abstract: Collagen mimetic peptides (CMPs) self-assemble into a triple helix reproducing the most fundamental aspect of the collagen structural hierarchy. They are therefore important for both further understanding this complex family of proteins and use in… read more here.

DOI: 10.1021/acs.biomac.2c00856
Abstract: Cation-π interactions play a significant role in the stabilization of globular proteins. However, their role in collagen triple helices is less well understood and they have rarely been used in de novo designed collagen mimetic… read more here.

DOI: 10.1021/acs.biomac.4c01455
Abstract: Developing collagen-mimetic peptides (CMPs) with short triple helices and fibril-forming ability remains challenging. Herein, we stabilized short CMPs (3-6 GPO repeats) by attaching extended aromatic π-system─fluorenyl groups at the N-terminus and tyrosine at the C-terminus.… read more here.

DOI: 10.1021/jacs.2c12931
Abstract: The folding of collagen is a hierarchical process that starts with three peptides associating into the characteristic triple helical fold. Depending on the specific collagen in question, these triple helices then assemble into bundles reminiscent… read more here.

DOI: 10.1371/journal.pone.0266035
Abstract: In meiosis, cells undergo two sequential rounds of cell division, termed meiosis I and meiosis II. Textbook models of the meiosis I substage called pachytene show that nuclei have conspicuous 100-nm-wide, ladder-like synaptonemal complexes and… read more here.
