[[http://www.uniprot.org/uniprot/BIODA_ARATH BIODA_ARATH]] Bifunctional enzyme that catalyzes two different reactions involved in the biotin biosynthesis. Catalyzes a mechanistically unusual reaction, the ATP-dependent insertion of CO2 between the N7 and N8 nitrogen atoms of 7,8-diaminopelargonic acid (DAPA) to form an ureido ring. Catalyzes the transfer of the alpha-amino group from S-adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA).
