Abstract

Phytate, also known as myoinositol hexakisphosphate, exhibits anti-nutritional properties and possesses a negative environmental impact. Phytase enzymes break down phytate, showing potential in various industries, necessitating thorough biochemical and computational characterizations. The present study focuses on Obesumbacterium proteus phytase (OPP), indicating its similarities with known phytases and its potential through computational analyses. Structure, functional, and docking results shed light on OPP's features, structural stability, strong and stable interaction, and dynamic conformation, with flexible sidechains that could adapt to different temperatures or specific functions. Root Mean Square fluctuation (RMSF) highlighted fluctuating regions in OPP, indicating potential sites for stability enhancement through mutagenesis. The systematic approach developed here could aid in enhancing enzyme properties via a rational engineering approach. Computational analysis expedites enzyme discovery and engineering, complementing the traditional biochemical methods to accelerate the quest for superior enzymes for industrial applications.

Obesumbacterium proteus 植酸酶的结构和功能特性：一项全面的模拟研究。

植酸又称肌醇六磷酸，具有抗营养特性，对环境有负面影响。植酸酶能分解植酸，在各行各业中显示出潜力，因此有必要对其进行全面的生物化学和计算表征。本研究以 Obesumbacterium proteus 植酸酶（OPP）为重点，通过计算分析指出其与已知植酸酶的相似性及其潜力。结构、功能和对接结果揭示了 OPP 的特征、结构稳定性、强而稳定的相互作用以及动态构象，其灵活的侧链可适应不同温度或特定功能。均方根波动（RMSF）突出了OPP的波动区域，表明了通过诱变增强稳定性的潜在位点。这里开发的系统方法有助于通过合理的工程方法增强酶的特性。计算分析加速了酶的发现和工程化，补充了传统的生物化学方法，加快了工业应用中对优质酶的追求。
