Recombinant garlic alliin lyase was produced in Escherichia coli, Sacc
haromyces cerevisiae, and Pichia pastoris. A cDNA clone was obtained f
rom garlic bulbs by PCR and introduced into suitable bacterial and yea
st expression vectors. The recombinant alliin lyase forms inclusion bo
dies in all three host organisms, which are deposited in the cytoplasm
. After cell ly sis and harvesting by centrifugation, the inclusion bo
dies were solubilized in Zwittergent 3-14 solution and refolded by ste
pwise dilution. Specific alliin lyase activity could be recovered by t
his procedure.
