Amino acids study guide BCH452-05 Section I. Knowing what you are talking about. 1. Know structures of: all 20 amino acids that appear in proteins. PLP and PMP pteridine ring structure isoalloxazine ring structure THF adoMet carbamoyl phosphate ornithine citrulline arginosuccinate urea fumarate 2. Where do the atoms of the purine ring come from? Section II. Pathways and processes. 1. What oxidized sources of nitrogen are found in the environment, and what enzymes are responsible for reduction of these forms of nitrogen to ammonia? 2. Draw the overall reaction scheme for the reduction of N 2 to 2 NH 3 by the combined action of dinitrogenase reductase and dinitrogenase. How many electrons are transferred to N 2 to produce NH 3 ? Are there any other products of the reduction reaction? How many ATP are consumed in the reduction of N 2 to NH 3 ? What are the intermediates in the stepwise reduction of N 2 to 2 NH 3 at the active site of nitrogenase? What prosthetic groups are involved in this reduction? 3.
