Prof. Tadhg Begley Texas A&M University Monday, April 9, 2018 - 11:15am Chemistry Building, Room 400 Inorganic Seminar CMS Seminar Since its discovery, in the early 1930s, the chemistry of riboflavin has been studied in great detail. It is therefore surprising that several new flavin-mediated reactions have been discovered over the past few years. My lecture will focus on three reactions where riboflavin is used as a substrate in a biosynthetic pathway. These reactions are involved in riboflavin catabolism, Vitamin B12 biosynthesis and roseoflavin biosynthesis.
