Abstract
The present invention provides a method for evaluating the ability of a compound to inhibit protoporphyrinogen oxidase activity with a host cell deficient in protoporphyrinogen oxidase production which has been transformed with a vector comprising a DNA fragment encoding a protoporphyrinogen oxidase. Transformed cells are grown in protoheme-free medium in the presence and absence of test compounds and growth rates measured under these condition are compared to determine if inhibition has occurred.
