Identifying genetic sequences
« on: March 21, 2017, 11:45:30 PM »
How do I identify conservative sequences in this protein sequence?

None of it looks conservative to me because it is not repeating itself? I'm not sure what to do with this.

Do you mean conserved? If so, you can't with just that. You need to perform a CLUSTALW alignment or similar to identify the portions that are conserved across species.

In biology, sequences that are conserved are sequences that are similar across different related species.  It looks like you posted a portion of a sequence alignment between two different protein species (specifically, it looks like you posted an alignment in FASTA format).  You can use a tool like http://www.bioinformatics.org/sms2/color_align_cons.html to look at the two protein sequences together to see which regions of the proteins are identical  or nearly identical (conserved) and which look very different.
