GrdE and PrdA of Clostridium sticklandii are subunits of glycine reductase and D-proline reductase, respectively, that are processed post-translationally to form a catalytic active pyruvoyl group. The cleavage occurred on the N-terminal side of a cysteine residue, which is thus the precursor of a pyruvoyl moiety. Both proproteins could be over-expressed in Escherichia coli and conditions were developed for in vitro processing. GrdE could be expressed as full-size protein, whereas PrdA had to be… CONTINUE READING
