Rationale of today’s work: Delegate jobs to each group member and begin researching promoter sequences for the phages containing genes in pham 7442. This pham has 16 members, all of which are in the AO cluster. We will give each member about 5 genes to thoroughly investigate through DNA Master’s Promoter prediction and NCBI blast. This time, however, we will be focusing on running the promoter prediction for the gap before the gene itself. Previously, we ran the promoter prediction on the gene itself, which was not very useful since promoters are typically found previous to the actual gene.
Tools used and/or Methods: PhagesDB glossary, Phamerator, DNA Master, NCBI

Conclusion: All the genes in the pham are scaffolding proteins and are preceded by hypothetical proteins. However, there was not a very clear correlation in the promoter sequences that I annotated. The other two members in my team have annotated the other 12 genes, so I need to look at those, too, when making generalizations and looking for a correlation. Our goal is to have all 18 phages in the pham blasted and their promoter sequences predicted.
Next Steps: Next week, we want to compare our results from the blasts and promotor predictions. If time allows, we will begin running various programs to determine the percent CG in the promotor sequences.
