Common Name7,8-Diaminononanoate
Description7,8-diaminononanoate (or DAPA) is an intermediate in biotin biosynthesis. It is a substrate for Adenosylmethionine-8-amino-7-oxononanoate aminotransferase (or bioA). This enzyme 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). The reaction is S-adenosyl-L-methionine + 8-amino-7-oxononanoate = S-adenosyl-4-methylthio-2-oxobutanoate + 7,8-diaminononanoate. DAPA is a simple intercalator, much like the widely studied 9-aminoacridine. (PMID 16180206 ; 16984394)
