Biotin biosynthesis ii

Biotin, synthesized in plants, is essential to plant growth and development. Bacteria also synthesize biotin, and it is thought that bacteria resident in the large intestine may synthesize biotin that is absorbed and utilized by the host organism. Synthesis starts from two precursors, alanine and pimeloyl-CoA. These form 7-keto-8-aminopelargonic acid (KAPA).
