B6db families:
Description Kynureninase.
Notes The family encompasses bacterial, fungal and animal genes (the activity has not been described in other organisms).
Note that many fungi contain two kinureninase genes - presumably, one encodes an inducible enzyme, whereas expression of the other is constitutive.
