Protein

Lysine 5,6-aminomutase beta subunit

Gene

kamE

Organism
Acetoanaerobium sticklandii (strain ATCC 12662 / DSM 519 / JCM 1433 / NCIMB 10654) (Clostridium sticklandii)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the migration of the L-beta-lysine and D-lysine epsilon amino group to the delta carbon to produce 3,5-diaminohexanoate and 2,5-diaminohexanoate, respectively.2 Publications

Catalytic activityi

(3S)-3,6-diaminohexanoate = (3S,5S)-3,5-diaminohexanoate.1 Publication
D-lysine = 2,5-diaminohexanoate.2 Publications

Cofactori

Protein has several cofactor binding sites:
  • adenosylcob(III)alamin2 Publications
  • pyridoxal 5'-phosphate2 Publications

Enzyme regulationi

Rapidly inactivated in the presence of D-lysine and to a lesser extent in the absence of adenosylcobalamin (Adocbl). Activity is stable in the presence of Adocbl when D-lysine is absent. Adocbl imparts thermal stability at 37 degrees Celsius.1 Publication

Kineticsi

  1. KM=6.6 µM for adenosylcobalamin (for recombinant alpha and beta subunits expressed together in E.coli to overcome presence of corrinoids in native system)1 Publication
