Only 2% of the known natural products with acetylenic bonds area-alkynoates. Their polarized, conjugated triple bond is an optimal target for an enzymic hydration. Therefore they are good substrates for the enzymes involved in metabolism of acetylenic compounds, resulting in products that are suitable for bacterial growth. We isolated a Pseudomonas putida strain growing on 2-butynedioate as well as on propynoate, and determined the metabolic pathways of these two a-alkynoates.

In order to understand the roles of the epoxide hydrolases (EHs) in xenobiotic biotransformation in insects, we exam-ined the induction of EHs by exogenous compounds in Drosophila melangasterthird instar larvae. Among the chemicals tested, clofibrate, a phenoxyacetate hypolipider-mics drug, increased EH activity towardscis-stilbene oxide approximately twofold in larval whole-body homogenates. The same dose of clofibrate also induced glutathione S-transferase activity.
