Abstract

The venom of the Habu snake () is known to contain a diverse array of proteins and peptides, with a notable presence of phospholipase A (PLA) enzymes. These PLA enzymes have been extensively studied for their function and molecular evolution. Nevertheless, several aspects, such as the physical properties and the self-assembly mechanism of hierarchical structure from the nanoscale to the microscale with different chemical compounds, remain poorly understood. This study aims to fill this knowledge gap by investigating the behavior of enzyme components purified from venom in the presence of anionic [Pt(CN)] complexes, which have the potential for soft metallophilic interactions and interesting optical properties. The purified PLA isozymes were diluted in Dulbecco's phosphate buffered saline (D-PBS (-)) and combined with the anionic metal complex, resulting in the formation of microstructures several micrometers in size, which further grew to form fibrous structures. This novel approach of combining PLA enzymes with discrete functional metal complexes opens up exciting possibilities for designing flexible and functional supramolecular and biomolecular hybrid systems in aqueous environments. These findings shed light on the potential applications of snake venom enzymes in nanotechnology and bioengineering.

摘要

眼镜王蛇的毒液 () 中含有多种蛋白质和肽类,其中显著存在磷脂酶 A(PLA)酶。这些 PLA 酶因其功能和分子进化而被广泛研究。然而,仍有几个方面,如物理性质和不同化合物自组装成从纳米到微米尺度的层次结构的机制,人们知之甚少。本研究旨在通过研究从毒液中纯化的酶成分在阴离子 [Pt(CN)] 配合物存在下的行为来填补这一知识空白,这些配合物具有软金属亲合相互作用和有趣的光学性质。纯化的 PLA 同工酶在 Dulbecco 的磷酸盐缓冲盐水 (D-PBS (-)) 中稀释,并与阴离子金属配合物结合,形成几微米大小的微结构,进一步生长形成纤维结构。这种将 PLA 酶与离散功能金属配合物结合的新方法为设计在水相环境中具有灵活性和功能性的超分子和生物分子杂化系统开辟了令人兴奋的可能性。这些发现揭示了蛇毒酶在纳米技术和生物工程中的潜在应用。
