From HHPred, this gene hits HK97_gp10, a minor capsid protein and a tail protein. So one must ask which is it? HK97 is the prototype phage for understanding how the capsid is formed. The lab that studied it was the lab of Roger Hendrix, from the University of Pittsburgh. As we hit gp10 of HK97, I asked if they knew the function of that gene and they could not identify it in their studies. As per the Approved Function List, when you hit HK97_gp10, stick with Hypothetical Protein until someone finds more data to support a call.

My advice is to ask the IT administrator to set the preferences. Whatever they do, should stick.

Hi Robert,
Please check you DNA master preferences and make sure you follow #2 and #6 correctly.

Holly,
Exactly! You've got it!

Hi Holly,
hmmm. I think that Mopey_14 (stop codon 10436), can be called the scaffolding protein because of the InterPro hit at HHPred (Q38580). It is a 99.5% probability (evalue is e-12) and has protein homology to the scaffolding protein of SPP1 (evidence is from UniProt database.
Granted that the example used by the approved function list is D29, but your protein doesn't have to hit the example (and it doesn't, does it?)

Hi Amy,
There are lots of reasons why Glimmer and GeneMark don't call the same things exactly the same. Mostly their algorithms are different. and the math breaks down with small proteins. It is why we use both. And they can both miss a call and predict something that we throw away. If automation made the best calls, we would not be doing this one gene at a time.

Nancy,
It just takes a long time. In the meantime, it will look like it is not responding! Wait for the log that pops up long after you see 100% done.
Good luck!

In our investigations, we determined that a MerR-like HTH will have 3 helix-coil motifs followed by a "wing' of a coil-coil. As I review your seqeunce int he link above, I do not see the 'wing' with a coil-coil at the end. so i would call this a helix-turn-helix DNA binding protein.

Hi Joe,
It is common that minor tail genes contain enzymes that help get the phage attached to the cell wall. So it is common to find them containing collagen, beta-lactamse, peptidoglucan domain (to name a few) hits. The big genes (maybe 4-6 of them) following the tape measure protein are really the only genes we can call by synteny alone as "minor tail protein". If the genes following the tape measure are not big, we look for additional evidence and sometmes find it. this gene is 493 aa, so I think we are good!
