5.4.3.4
Activity 5.4.3.4
Description D-lysine 5,6-aminomutase
Notes Lysine 5,6-aminomutase, an adenosylcobalamin and pyridoxal-5'-phosphate-dependent enzyme, is made of two subunits.
PLP is inserted in the TIM-like barrel of the alfa subunit, but is covalently bound to a Lys residue of the Rossmann domain of the beta subunit.

Only sequences of the alfa subunit have been included in this family.
