Evan,
Keep in mind that the coding potential is based on a sample of the sequence from each genome, so why would you expect them to be the same? The use of comparative genomics is helpful and necessary here.
to prove the point, I just ran GeneMark on Stanktossa and got a different result than you did. Yes, coding potential is very important, but this shows you that it has to be thought of in context. The comparative genomics are impressive.

Evan,
Have you read this?

Both Glimmer and GeneMark use a sample of the target genome, so if you run them 10 times you MAY get some differences. Those differences occur most commonly when predicting 'small' genes. It is the primary reason we hand curate the genomes.

As for your question, please provide specifics: what gene, what genome, and any other pertinent data.

Thanks,
debbie

Hari,
Basically yes.
However, when you add gene "11" in HarperAnne, add the gene only in that frame. If you add a gene that starts at 10 and ends at 11 it will be difficult to see where to slip it. (But if you know that coordinates of the slippage, it won't matter.) Then go back and chagen the start and add regions when you have it figured out.

Claire,
It works!

Steve,
Most minor tail proteins are called by synteny. Sometimes there is no HHPred info to support the call. It is common to call the 4-5 genes "big" downstream of the tape measure "minor tail proteins". In addition, I think the phage genes that hit collagen are commonly minor tail proteins. So there has to be some similarity in the protein structure, but I don't know what that is. I would easily call Heather_gp18 a minor tail protein.

I think Ry Young (from Texas A&M) has papers written about multiple holins in the phages that he studies. It is just hard to know if a membrane protein is a holin. and if a pfam hit to holin is believable.

Cathy,
The owner of the file got hacked which is where that google sheet resided. I just learned of this today, so I am going to need some time to see if this attached list matches what was posted. In the meantime, here is the list I have.

Roy,
I think this is the same question as yours.

This refers specifically to BubbaBear_gp56. A question posed by Dr. Herren (Kansas State U): Isn't this a dihydrofolate reductase rather than a thymidylate synthase.


First I scanned this website http://www.ebi.ac.uk/interpro/entry/IPR012262
From this I learned that they often come together.
However, when both parts are there, I think it is a much larger protein, with PDB citing residues of 159-384 for the DR crystal structure and 1042 – 2084 residues for the TS structure.
It looks like this is aligning with the DR domains and not the TS. So I would call BubbaBear gp 56 a "dihydrofolate reductase"!
