'''7,8-diaminopelargonic acid synthetase''' (DAPAS) is part of the biotin biosynthesis pathway. DAPAS catalyzes the amino transfer from S-adenosylmethionine to 7-keto-8-pelargonic acid (KAPA) to produce S-adenosyl-4-methylthio-2-oxobutanoate and 7,8-diaminopelargonic acid. DAPAS is a pyridoxal phosphate (PLP)-dependent enzyme.<ref>PMID:12379100</ref> '''Bifunctional DAPAS/dethiobiotin synthetase''' (DAPS/DTBS) catalyzes the above reaction and the conversion of 7,8-diaminonanoate, ATP and CO2 to ADP, phosphate and dethiobiotin. | '''7,8-diaminopelargonic acid synthetase''' (DAPAS) is part of the biotin biosynthesis pathway.
