Comments [?]

Function Catalyzes a mechanistically unusual reaction, the ATP-dependent insertion of CO2 between the N7 and N8 nitrogen atoms of 7,8-diaminopelargonic acid (DAPA, also called 7,8-diammoniononanoate) to form a ureido ring.
Catalytic activity RHEA:15805: (7R,8S)-7,8-diammoniononanoate + ATP + CO2 = (4R,5S)-dethiobiotin + ADP + 3 H(+) + phosphate
EC 6.3.3.3
Cofactor Mg(2+)
Pathway Cofactor biosynthesis; biotin biosynthesis; biotin from 7,8-diaminononanoate: step 1/2.
Subunit Homodimer.
Subcellular location Cytoplasm.
Similarity Belongs to the dethiobiotin synthetase family.
