Beta-lysine 5,6-aminomutase

In enzymology, a beta-lysine 5,6-aminomutase (EC number|5.4.3.3) is an enzyme that catalyzes the chemical reaction

:(3S)-3,6-diaminohexanoate $ightleftharpoons$ (3S,5S)-3,5-diaminohexanoate

Hence, this enzyme has one substrate, (3S)-3,6-diaminohexanoate, and one product, (3S,5S)-3,5-diaminohexanoate.

This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring amino groups. The systematic name of this enzyme class is (3S)-3,6-diaminohexanoate 5,6-aminomutase. Other names in common use include beta-lysine mutase, and L-beta-lysine 5,6-aminomutase. This enzyme participates in lysine degradation. It employs one cofactor, cobamide.

tructural studies
