B-vitamin dependent metabolic enzymes

B-vitamin dependent metabolic enzymes represent a large and heterogeneous group of enzymes that require B vitamins—such as thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12)—as essential coenzymes[5][4][2][1]. These enzymes catalyze thousands of biochemical reactions crucial for cellular energy production, macromolecule biosynthesis, neurotransmitter generation, and detoxification. Their functions are central to physiology and disease. For example, pyridoxal phosphate-dependent enzymes (Vitamin B6) are critical for amino acid metabolism and neurotransmitter synthesis[4][3], while adenosylcobalamin-dependent enzymes (Vitamin B12) mediate isomerase and methyltransferase reactions[1]. Deficiencies in these vitamins or enzyme dysfunction can lead to diverse metabolic diseases, neurological disorders, anemia, and other conditions[5]. Because the term describes a category rather than a specific molecular entity, it should not be considered a canonical target for drug development; rather, individual enzymes within this group (e.g., pyruvate dehydrogenase, methylmalonyl-CoA mutase) may themselves be considered specific targets.
