Researchers from the US used a nicotine oxidizing enzyme called NicA2, found in the bacterium Pseudomonas putida. They modified it, adding to albumin - a common protein of the blood plasma of vertebrates. This allowed to increase the lifetime of the enzyme in the animals. It has been shown in rats that an enzyme oxidizing nicotine in the blood does not allow it to enter the brain and blocks its psychoactive properties. It is assumed that such a protein can be the basis for a new tool that helps to cope with nicotine addiction.
