Explain the assigned literature article (Nature, 2010, 464, 1077), as if another student in CHEM 130B was your audience. An important component of scientific writing is to be concise, so you will have a 1-page limit to give a complete and accurate explanation. Remember that you may need to read sources that are cited or look at the Supporting Material for a full understanding of the paper. Please focus on the biochemical aspects of the paper rather than the phylogenetic studies, making sure to include key experiments and results.
