Both ACHE, which is inhibited by soman, and OPAA, the enzyme that hydrolyzes soman, seem to be indifferent to the configuration around the C chiral center (1).
The subtitle of that report (3), "Nerve agent-detoxifying enzyme is a prolidase" leads us to ask whether this applies to the squid type OPAA as well.
05 ml purified OPAA (diluted sufficiently to give a measurable reaction rate) is added to 4.

All of the Pseudomonas readings were significantly greater than zero by the expedient of increasing the amount of enzyme, increasing the instrument sensitivity, or both; but with Tetriso in the role of substrate, a 50-fold increase of the amount of OPAA over that used with DFP, and full-scale absorbancy set at 0 to 0.
