Protein attributes

Sequence length	225 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (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) to form an ureido ring. Only CTP can partially replace ATP while diaminobiotin is only 37% as effective as 7,8-diaminopelargonic acid. Ref.6 Ref.7
Catalytic activity	ATP + 7,8-diaminononanoate + CO2 = ADP + phosphate + dethiobiotin. Ref.7
Cofactor	Magnesium.
Pathway	Cofactor biosynthesis; biotin biosynthesis; biotin from 7,8-diaminononanoate: step 1/2. HAMAP MF_00336
Subunit structure	Homodimer. Ref.7 Ref.9 Ref.10 Ref.13
Subcellular location	Cytoplasm HAMAP MF_00336.
Sequence similarities	Belongs to the dethiobiotin synthetase family.
