Thus, it is important to identify vitamin interacting residues in a protein.It is possible to detect vitamin-binding pockets on a protein, if its tertiary structure is known.Most of the aforementioned intermediates have only been isolated after esterification and in very small quantities.We use X-ray crystallography to study the three-dimensional structures of proteins.We are also particularly interested in the novel activities associated with two newly discovered catabolic pathways: one for each pyrimidines and one for purines.Purine utilization is initiated by a cyclohydrolase reaction.Systematic investigation of an entire biochemical pathway provides important clues about protein evolution.Our current emphasis is on multifunctional enzymes associated with these pathways that had not been previously characterized.

In past, many inhibitors have been designed against vitamin binding pockets in order to inhibit vitamin-protein interactions.Flavin-dependent monooxygenases and oxidoreductases are located at critical branch points in the biosynthesis and metabolism of cholesterol and vitamin D.The labelling patterns of metabolites from experiments with stable isotope-labelled precursors can be determined by NMR spectroscopy.The earliest tracer studies were conducted with deuterium in the 1930s [1].Author contributions ED designed and performed most of the experiments and analysis with support of ADL and SS; ADL performed mass spectroscopy analysis.
