Blasting Spacers

EXPLORATION OF THE IMPORTANT FINDINGS


CRISPR one results from CRISPR finder are shown below. I blasted all of the spacers using the nr/nt database and the results are shown below.

CrisperOne.jpg


Spacer One: TGCGTCGTCCGGTGGCCGTCAATAAATGTCGCAAGGG

No significant hits . . . lowest E-value is 5.9

Spacer Two: TCCTACGACCTCGTCGGCGTCAACGGCTGGCCCGA 

  Spacer2.jpg
  
 Archaeal BJ1 virus complete genome:  Good Article
 
 Spacer2222.jpg
 
 This is the protein sequence location that this match comes from in the virus:
 
 Archaealvirus.jpg
 
 Blasted this little sequence alignment section. . .  did not get any significant viral alignments except its own
 
 Did blastp to determine if hypothetical protein in archaeal BJ1 virus had hits in other viruses:
 
 Blastp4.jpg
 
 
 The rest of the hits are bacteria and are in coding protein sequences such as ABC transporter and ATP-binding protein.


Spacer Three: CACCCTACAACAGGTGAAATCTACCAGACAAAAGA

Spacer3.jpg

All of these hits are bacteria and the bacteria hits are part of coding proteins such as conserved hypothetical protein; putative membrane protein, which I did a blastp for and found no viral matches

Other things i want to do: 

  compare our species spacers with themselves
  look to see if these blast results show hits to any other halophiles
  look at spacer length and number between our species and others??
  any known viruses that infect halophiles??

 blast the known viral genome against the nr/nt database and it comes up with matches:
