  • Picolinic acid is oxidized by cells and extracts of Arthrobacter picolinophilus to 6-hydroxypicolinic acid. The enzyme involved is a particulate hydroxylase which appears to incorporate the hydroxyl group of water into the substrate. The enzyme was purified about 60-fold. The molecular weight as determined by gel filtration was 230 000 daltons. Activity of the purified enzyme was stimulated by ferrous ions and was inhibited by quinacrine. Flavin mononucleotide reversed the inhibition by… CONTINUE READING
