What kind of images? Do you mean the plaque or EM pic on phagesDB or something else?

the program needs to update to get to the right version for setting preferences. if the progam isn't avilable at cobamide…. Go the DNA master page on phagesDB. Click on the word "here" in the second sentence to download the install program.

Hi Martin,
Are you on a mac or pc?
Do you have excel? iI you do not, uncheck the load into excel box and see if that works. if not, send your .dnam5 files to me.

Hi Martin,
The final file is a correctly formatted .dnam5 file. It is not a "profile".
What file are you working with?
Here is the final file submission instructions.

Once I know what you are working with i ca help more.

What you did was not wrong. It is good we do things different, though it may seem confusing. I look for the most basic structural genes in every phage and when I am missing what I expect to find, I just look elsewhere.

Hi Dane,
Sorry for the delay in this response. I WOULD call this a capsid maturation protease because of the hit to the UniProt hit to gp 15 in D29. Probability and Evalue is great and these gene functions were assigned by Drs. Hatfull and Hendrix back in the day. It is also in the right place and is involved in capsid assembly.
debbie. BTW, i hit no MuF proteins.

I would think that the hits to the Bacillus and E.coli phages are just as compelling. I would call this a minor tail protein.

Hi Marie,
I think we have enough evidence to call this the capsid maturation protease (CMP). It hits a structural protein of a lactobacillus phage. Which then makes debate whether this is a head or tail protein. The next hit is to gp7 of SPP1 - the papers written about that gene are capsid proteins involved in packaging….. that makes me think not quite in the final virion structure….
And then we hit the capsid maturation protease of D29 (gp15). That hit is at 97%, with an e-value of 10-3. So while that hit is not the best, it is the most descriptive for me and jives with the stronger hits. AND then look at where this gene is in the genome. In between portal and scaffolding!! I think I would be OK calling is a CMP. what do you think?

Hi Susan,
Holin is one of those gens that is a delight to call, but difficult. it doesn't surprise me that we were not able to call the holin genes historically.
Holin genes are many times now callable because of their pfam hits. In this case, that is exactly true. According to deep TMHMM, there are 3 genes directly upstream of the major tail protein that have more than one transmembrane domains. The first of those - the one I think you are pointing to - is a pfam hit to a holin as you describe. I want to call it a holin and the next 2 transmembrane proteins.
I would not be surprised if they too are involved in the holin/lysin function for this phage.

Here is paper to help!

Hi Fred and Chris,
am not convinced that this isn't something that we could call an HNH.
I just skimmed a paper, , that seems to suggest that the motif could be HNH, HNK, or HNN.
In general, there are a number of endonuclease 'types' that we have not addressed. I am not sure we have a complete enough understanding to differentiate.
