== Function ==
[https://www.uniprot.org/uniprot/BIOD1_ECOLI BIOD1_ECOLI] 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. Only CTP can partially replace ATP while diaminobiotin is only 37% as effective as 7,8-diaminopelargonic acid.<ref>PMID:4892372</ref> <ref>PMID:4921568</ref>

== Publication Abstract from PubMed ==
The crystal structures of two complexes of dethiobiotin synthetase, enzyme-diaminopelargonic acid-MgADP-AlF3 and enzyme-dethiobiotin-MgADP-Pi, respectively, have been determined to 1.8 A resolution. In dethiobiotin synthetase, AlF3 together with carbamylated diaminopelargonic acid mimics the phosphorylated reaction intermediate rather than the transition state complex for phosphoryl transfer. Observed differences in the binding of substrate, diaminopelargonic acid, and the product, dethiobiotin, suggest considerable displacements of substrate atoms during the ring closure step of the catalytic reaction. In both complexes, two metal ions are observed at the active site, providing evidence for a two-metal mechanism for this enzyme.
