Specificity

The purified antibiotic has strong antifungal activity and is less efficient against bacteria or yeast.

Application

Pyrrolnitrin from Pseudomonas cepacia has been used as a standard in the detection of pyrrolnitrin in Serratia marcescens cell culture extract.

Biochem/physiol Actions

Pyrrolnitrin blocks the terminal electron transport between succinate or reduced NADH and coenzyme Q. In mitochondria preparations of S. cerevisiae, the antibiotic inhibited succinate oxidase, NADH oxidase, succinate cythochrome C reductase, and NADH-cytochrome C reductase. Pyrrolnitrin is involved in many cellular processes such as oxidative stress, electron transport, DNA and RNA synthesis.
Pyrrolnitrin is a metabolite, produced by Pseudomonas sp.

The unicellular alga Chlamydomonas reinhardtii and the bacterium Pseudomonas protegens serve as a model to study the interactions between photosynthetic and heterotrophic microorganisms. P. protegens secretes the cyclic lipopeptide orfamide A that interferes with cytosolic Ca2+ homeostasis in C. reinhardtii
