Protein

L-Lysine--8-amino-7-oxononanoate transaminase

Gene

bioK

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the transfer of the alpha-amino group from L-lysine to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA). B.subtilis is the only bacterium known to utilize L-lysine as an amino donor in the biosynthesis of DAPA.1 Publication

Catalytic activityi

L-lysine + 8-amino-7-oxononanoate = (S)-2-amino-6-oxohexanoate + 7,8-diaminononanoate.1 Publication

Cofactori

pyridoxal 5'-phosphate2 Publications

Enzyme regulationi

Inhibited by 7-keto-8-aminopelargonic acid at concentrations above 80 µM.1 Publication

pH dependencei

Optimum pH is 8.6.1 Publication

Pathwayi: biotin biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 7,8-diaminononanoate from 8-amino-7-oxononanoate (SAM route).1 Publication
Proteins known to be involved in this subpathway in this organism are:
  1. L-Lysine--8-amino-7-oxononanoate transaminase (bioK)
This subpathway is part of the pathway biotin biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 7,8-diaminononanoate from 8-amino-7-oxononanoate (SAM route), the pathway biotin biosynthesis and in Cofactor biosynthesis.
