Endogenous metabolic enzyme

Endogenous metabolic enzymes represent a diverse group of proteins that catalyze essential biochemical reactions within the body, including the breakdown of nutrients and the synthesis of cellular components [1]. This category includes major enzyme families such as Cytochrome P450 (CYP), kinases, and proteases, which are critical for maintaining physiological homeostasis and processing xenobiotics [2]. While many individual enzymes within this group are well-characterized therapeutic targets, the collective term "various endogenous metabolic enzymes" is non-specific and typically used when the exact molecular target is unknown or when a drug has pleiotropic effects across multiple metabolic pathways [3]. Consequently, this designation is insufficient for precise drug-target interaction modeling or specific clinical indications [4]. In a clinical context, identifying the specific enzyme involved is crucial for understanding a drug's efficacy and safety profile [5]. These enzymes are involved in a wide range of diseases, from metabolic syndromes to cancer, where their dysregulation leads to pathological states [1]. Drugs targeting these enzymes often work through competitive or non-competitive inhibition to restore normal metabolic flux [2].
