This is the first of a three-part video series. It was made in May of 2015 and it represents the work of my BIOL375/Molecular Genetics class and several students working in my lab at Augustana College. In this video, I describe how we arrived at the prediction that M. ruber follows the usual sequence in synthesizing the amino acid proline from glutamate. We use the bioinformatics programs and online lab manual associated with GENI-ACT (an NSF-funded project).
