CC -!- FUNCTION: Catalyzes the conversion of dethiobiotin (DTB) to biotin by
CC the insertion of a sulfur atom into dethiobiotin via a radical-based
CC mechanism. {ECO:0000256|HAMAP-Rule:MF_01694}.
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 -!- FUNCTION: Catalyzes two activities which are involved in the biotine
CC biosynthesis: the conversion of dethiobiotin (DTB) to biotin by the
CC insertion of a sulfur atom into dethiobiotin via a radical-based
CC mechanism, and the transfer of the alpha-amino group from S-adenosyl-L-
CC methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-
CC diaminopelargonic acid (DAPA). {ECO:0000256|ARBA:ARBA00003991}.
