Picolinic acid hydroxylase of Arthrobacter picolinophilus

Canadian Journal of Microbiology, 1974
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.

Immunobiology of Picolinic Acid

1996
Exposure of various cell types to IFN results in increased enzymatic activities leading to the breakdown of tryptophan and evidence exists to suggest that the catabolism of tryptophan may be connected to the biological effects of interferon (Carlin et al., 1989.

THE CRYSTAL STRUCTURE OF PICOLINIC ACID

Chemistry Letters, 1973
Abstract The crystal structure of picolinic acid was determined by a three-dimensional X-ray analysis. The molecules are linked by two symmetric double minimum hydrogen bonds with a small potential barrier, N–H–N and O–H–O,and form a zig-zag chain.

Microbial oxidation of kynurenic, xanthurenic and picolinic acids

Biochimica et Biophysica Acta, 1963
Abstract 1. 1. Resulta of a study of the degradation of kynurenic acid by an Aerococcus are in agreement with a reaction sequence proposed for Pseudomonas by other workers. This sequence includes Compounds I and II below. 2. 2. Partial inhibition of oxidation of kynurenic acid by cell suspensions caused an accumulation of pyruvate with ...

Picolinic Acid in Acrodermatitis Enteropathica

Journal of Pediatric Gastroenterology and Nutrition, 1984
SummaryThree children with acrodermatitis enteropathica (AE) were treated with oral zinc dipicolinate (zinc‐PA). The daily dose of zinc required to prevent exacerbations, when administered as the dipicolinate complex, was one‐third the minimum amount of zinc required as the sulfate salt. The concentration of picolinic acid in the plasma of asymptomatic
