Cu(II) and Ni(II) Interactions with the Terminally Blocked Hexapeptide Ac-Leu-Ala-His-Tyr-Asn-Lys-amide Model of Histone H2B (80–85) by Katerina Panagiotou, Maria Panagopoulou, Tilemachos Karavelas, Vassiliki Dokorou, Andrew Hagarman, Jonathan Soffer, Reinhard Schweitzer-Stenner, Gerasimos Malandrinos, Nick Hadjiliadis

“…The N- and C-terminal blocked hexapeptide Ac-Leu-Ala-His-Tyr-Asn-Lys-amide (LAHYNK) representing the 80–85 fragment of histone H2B was synthesized and its interactions with Cu(II) and Ni(II) ions were studied by potentiometric, UV-Vis, CD, EPR, and NMR spectroscopic techniques in solution. …”

Insight into the structure of antitubercular Callyaerins: conformational studies and synthesis of a unique dehydroamino acid, β-aminodehydroalanine by Karolina Banaś, Paweł Lenartowicz, Dawid Siodłak

“…Two conformations, β2 (φ,ψ ~ − 120°, 20°) and α (φ,ψ ~ − 70°, − 15°) are predicted as the most preferable, regardless of the geometry of isomer (Z/E), polarity of environment, and order (2°/3°) of C-terminal amide group. The N–H⋯O hydrogen bond involving the N–H group in the β position of the side chain as a donor is a significant stabilizing factor. …”
