no, we are not calling those three small proteins minor tail proteins any longer. Only the lengthy ones.

Hi Maria,
I think you can use terminase small subunit here.

This one has me stumped– it hits the trifecta of things I don't like to put in official function names: a TLA, a structural motif, and a phenotype.

I really dislike TLAs in the functional annotations, unless it is one like "DNA" which is totally unambiguous and everyone knows. You are right that DPS is simplistic and uninformative.

re the ferritin component— is it actually binding iron? I dislike naming functions after the structural fold of something that does something completely different—

And DNA protection during starvation could be accomplished by a number of proteins with different shapes.

Hi Maria,
It is always worth asking Becky and Dan to double-check the sequence when you find a disruption in a gene with a known function. We do find errors in sequences, especially those that were sequenced with the Ion Torrent technology. It is pretty rare in those sequenced with Illumina.

If the sequence is legitimate, you could annotate it is RtcB-like ligase, truncated. As you noted, we don't add frameshifts to the annotations, other than for the tail assembly chaperones.

I agree. Sounds like some revisions I need to make in those revisions. Thanks!

Hi Sarah,
How similar is it to MPME1? And does it have the rest of the MPME features? If so, it sounds like you may have MPME 3….

Hi Chris,
All of the mass-spec evidence that we have indicates that when there are two start codons back-to-back, it is the downstream one that is correct.

So sounds like you should go with the ATG in this case.

Sounds good to me.

Sorry it took me so long to get back to this— I think the way forward is to call them tail assembly chaperones and not to put in the slip.

We probably need to remove it from the other two, as well– they are all probably using the same site and we can't identify it at this time.
