Abstract

A theoretical conformational analysis was performed to study the conformational possibilities for the casoxin C molecule (Tyr1–Ile2–Pro3–Ile4–Gln5–Tyr6–Val7–Leu8–Ser9–Arg10–OH). The potential function of the system was chosen as a sum of non-valence, electrostatic, and torsion interactions, and the energy of hydrogen bonds. The low-energy conformations of the casoxin C molecule were found, the values of dihedral angles of the main and side chains of the amino acid residues that make up the molecule were determined, and the energy of intra- and interresidual interactions was estimated. It has been shown that the spatial structure of the casoxin C molecule is represented by conformations of eight shapes of the peptide backbone. The results obtained can be used to elucidate the structural and structural-functional organization of casoxin molecules.

Casoxin C 分子的空间结构
为了研究 casoxin C 分子(Tyr1-Ile2-Pro3-Ile4-Gln5-Tyr6-Val7-Leu8-Ser9-Arg10-OH)的构象可能性,我们进行了理论构象分析。系统的势函数被选为非价、静电和扭转相互作用以及氢键能量的总和。找到了 Casoxin C 分子的低能构象,确定了组成分子的氨基酸残基主链和侧链的二面角值,并估算了残基内和残基间相互作用的能量。结果表明,卡索辛 C 分子的空间结构由肽骨架的八种构象表示。所获得的结果可用于阐明 casoxin 分子的结构和结构功能组织。
