B6db families: b
Description L-cysteine desulfidase (family b)
Notes This subfamily encompasses fold-type II enzymes for which a L-cys desulfhydrase activity has been reported.
Bacterial and plant enzymes probably evolved independently, even though both are clearly derived from cysteine synthases (
