Lab 4 – Phamerator
Date of Lab: 01/31/17
Rationale: The purpose of the lab was to practice genome annotation and learn how to use Phamerator.
Tools used: DNA master, NCBI, Phamerator
Procedures:
- Open the software Phamerator through virtual box and login with the password “phamerator”.
- Under “Phages” tab> search the interested gene (It will allow you to look at multiply genes at the same time) > MAP
- the number in the colored box = gene number
- number above the box = pham number
- number in (#) = number of members in that pham
- lines on the graph: identifying sequence that are similar on other part/ duplication/different place/ phage
- upper gene= forward
- lower gene = reverse
- If we pointed at the gene/the rectangle, it would show the function of the gene(only apply on some genes)
- Annotate the assigned gene (gene 22)
Conclusion:
We got to learn to use a new tool to help us to annotate the genes with more details and have more practice on annotating the genes.
Notes:
- each ruler = genome
- rectangle = auto annotated gene
- high gene density
- shouldn’t have too many gap/overlap–should be packed
- there will be gap for promoter between genes
- If it is a perfect match :
- query coverage ~200%
- E value ~ 0
- Long DNA = tap measure gene
- Short gene = regulator
- F = function
- Fs = function source: blast, pharmarater, HHpred, cdd(conserved domine), record best blast
