CC   -!- FUNCTION: Catalyzes the transfer of the alpha-amino group from S-
CC       adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to
CC       form 7,8-diaminopelargonic acid (DAPA). It is the only aminotransferase
CC       known to utilize SAM as an amino donor. {ECO:0000256|HAMAP-
CC       Rule:MF_00834}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(8S)-8-amino-7-oxononanoate + S-adenosyl-L-methionine =
CC         (7R,8S)-7,8-diammoniononanoate + S-adenosyl-4-methylsulfanyl-2-
CC         oxobutanoate; Xref=Rhea:RHEA:16861, ChEBI:CHEBI:16490,
CC         ChEBI:CHEBI:59789, ChEBI:CHEBI:149468, ChEBI:CHEBI:149469;
CC         EC=2.6.1.62; Evidence={ECO:0000256|HAMAP-Rule:MF_00834};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000256|ARBA:ARBA00001933,
CC         ECO:0000256|HAMAP-Rule:MF_00834};
CC   -!- PATHWAY: Cofactor biosynthesis; biotin biosynthesis; 7,8-
CC       diaminononanoate from 8-amino-7-oxononanoate (SAM route): step 1/1.
CC       {ECO:0000256|HAMAP-Rule:MF_00834}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00834}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00834}.
CC   -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC       aminotransferase family. BioA subfamily. {ECO:0000256|HAMAP-
CC       Rule:MF_00834}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC       feature annotation. {ECO:0000256|HAMAP-Rule:MF_00834}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
