Is there a correlation between similar cluster phages’ tandem repeats within the tape measure protein and its location within that gene? Jonathan Kindberg BNFO 301 04/24/2013
Tape Measure Protein • Tail of a phage is used to inject it’s DNA into the host bacterium, which is the beginning of lysis. • The tape measure protein got its name because the length of the corresponding gene is proportional to the length of the phage's tail: a fact shown by actually copying or splicing out parts of DNA in exemplar species [1]. • Tandem Repeats are the tell tale sign of the tape measure protein
Tandem Repeats • Tandem repeats occur when more than one nucleotide is repeated • The nucleotide repeats lie adjacent to each other within the gene. • TR example: ATGTAAGCTAAGCTAAGCTTG • The tandem repeat consists of TAAGC
Experimental Procedure • Phagesdb.org to look at similar cluster phages • Look for tandem repeats in he genomes to find the tmp gene with the use of PhAnToMe/BioBIKE • PhAnToMe/BioBIKE functions will include SEQUENCE-SIMILAR-TO and ALIGNMENT-OF • Scatter plot of the phages tandem repeats vs. location in their genome will be graphed • Analysis of experimental findings
Experimental Tools • Phagesdb.org • PhAnToMe/BioBIKE • Tandem Repeat Finder • Blast • Oracle Virtual Machine • Allows me to find phamerator maps of annotated phages.
Results • TBD
