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:0000255|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:0000255|HAMAP-Rule:MF_00834};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|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:0000255|HAMAP-Rule:MF_00834}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00834}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00834}.
CC -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC aminotransferase family. BioA subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_00834}.
