Enzymes have long been recognized as powerful catalysts that drive biological reactions with exceptional efficiency and specificity. Their ability to perform complex chemical transformations under mild conditions makes them valuable tools for a wide range of biotechnological applications. Over the years, advances in molecular enzymology techniques have significantly contributed to our understanding of enzyme function and have paved the way for harnessing the enzymatic power for diverse biotechnological purposes [1]. The field of molecular enzymology focuses on studying the mechanisms by which enzymes catalyze reactions and exploring their structurefunction relationships [2]. This knowledge is crucial for rational enzyme design, engineering, and optimization to meet the specific requirements of various biotechnological applications. By uncovering the intricate details of enzyme mechanisms, researchers can enhance enzyme performance, expand substrate specificity, improve stability, and tailor enzyme properties to suit specific industrial needs [3]. One area of significant progress in molecular enzymology is the application of structural biology techniques. X-ray crystallography, cryo-electron microscopy, and nuclear magnetic resonance spectroscopy have provided detailed insights into the three-dimensional structures of enzymes and their complexes [4]. These structural studies have revealed the arrangement of active sites, the conformational changes that occur during catalysis, and the interactions between enzymes and their substrates or cofactors. Such knowledge has been crucial for the rational design and engineering of enzymes with enhanced properties and for understanding the molecular basis of their catalytic activities. Computational approaches have emerged as indispensable tools in molecular enzymology, complementing experimental techniques [5]. Molecular dynamics simulations allow researchers to explore enzyme dynamics, conformational changes, and interactions at an atomic level. These simulations provide valuable insights into the mechanisms of enzyme catalysis, the role of specific residues, and the energetics of reaction pathways [6]. Computational methods, such as docking studies and quantum mechanics/molecular mechanics calculations, aid in the rational design of enzyme variants with improved properties or the prediction of enzyme-substrate interactions [7]. The synergy between computational and experimental approaches has accelerated the development of novel enzymes with tailored functionalities. Enzymatic assays and high-throughput screening methods have revolutionized the discovery and characterization of enzymes for biotechnological applications. Enzymatic assays provide a means to measure enzyme activity, substrate specificity, and kinetics [8]. Techniques like rapid-quench and stopped-flow kinetics enable the observation of transient reaction intermediates and the elucidation of complex reaction mechanisms. Highthroughput screening methods, coupled with advances in DNA sequencing technologies, allow for the efficient screening of large enzyme libraries to identify variants with desired properties [9]. This approach accelerates the discovery of novel enzymes and expands the enzymatic toolbox available for biotechnological applications. In addition to enzyme discovery and optimization, molecular enzymology has played a crucial role in the development of enzyme immobilization techniques and the engineering of biocatalysts [10]. Immobilization methods, such as enzyme encapsulation, surface immobilization, or covalent attachment, improve enzyme stability, facilitate separation, and allow for enzyme recycling. Molecular enzymology approaches guide the selection of suitable immobilization strategies, taking into account the enzyme's structure, stability, and activity. Furthermore, enzyme engineering techniques, including directed evolution and rational design, have been employed to enhance enzyme properties, such as substrate specificity, thermal stability, pH tolerance, and catalytic efficiency.
