Synthesis and Characterization of Pterin-Based Molybdenum Cofactor

Posted July 28, 2011

Abstract: Suyin Lee Mentor: Dr. Sharon Burgmayer Molybdenum is an essential transition element that forms a catalytic center of enzymes such as nitrogenase, nitrate reductases, sulfite oxidase and xanthine oxidoreductases. Some of these enzymes play important roles in carbon, nitrogen and sulfur cycles in the ecosystem while others are essential for proper human neurological development. […]

Synthesis and Characterization of Molybdenum Tetrasulfide Complexes and Pterinyl Alkyne

Posted July 26, 2011

Abstract: Suyin Lee Mentor: Dr. Sharon Burgmayer The molybdenum co-factor (Moco) forms the active site of redox reactions in all eukaryotic molybdenum enzymes such as nitrogenase, nitrate reductases, sulfite oxidase and zanthin oxidoreductases. Two different systems, molybdopterin (Figure 1) and iron-molybdenum co-factor have been found to control redox and catalytic functions of molybdenum which serves […]
