Biotin Biosynthesis in Bacteria

The video tutorial by Kevin Tokoph on Catalyst University explores the biotin cycle and its biosynthesis in bacteria. It explains how mammals obtain biotin through diet, as they cannot synthesize it. The tutorial delves into the biosynthetic pathway of biotin, highlighting the role of pimeloyl-ACP and various enzymes like BioH, BioC, BioF, BioA, BioD, and BioB. The process spans cellular compartments in bacteria, and the synthesized biotin travels up the food chain to humans. The video emphasizes the importance of biotin in enzymatic functions.
