They never emailed me back but we seem to be ok if we are rather gentle with HHPRED. Specifically, don't:
-copy over a previous input and resubmit under a new ID
-launch multiple HHPRed searches simultaneously under the same browser

Sometimes, it seems to help to erase the previous job before entering a new job and launching.

It's nice that I can still find inventive ways to break things.

Um, has anyone ever gotten kicked out of HHPRED? My student and I were launching multiple HHPRED jobs (3-4) in multiple tabs and now both of our IPs have been blocked apparently. I can search on a different laptop but when we search on those two laptops, we get "ERROR!". We tried to clear cookies and restart and nope, HHPRED still throws the error, so I think it might be IP-based. I get the error whether I am logged into an HHPRED account or not.

If we are the first, um, well, word to the wise.

Hi, we had this discussion when we annotated MarioKart a little over a year ago. I am not sure that there is not a frameshift but just felt like there wasn't enough evidence to call it.
Nhagos and Sours have 4 Gs around the end of gene 21 that is the region identified as the slippery sequence.

Does yours have Pham 113375 or 115039? It might be worth tracking it by Pham rather than by cluster.

Thanks Vic!
We will try it out and report back on how it goes.

Hi, did you ever have any luck with this? I have a student who has apparently lost their phage that they isolated a couple of weeks ago. We'd like to take his old plaques and PB and amplify them back up. Thanks.

Thanks, Vic. That is helpful. We were losing some DNA and weren't sure if we were getting capsid denaturation from the proteinase K. Different protocols seem to have wildly different proteinase K conditions.

Hi, the phage discovery has RNase/DNase/ProteinaseK treatment followed by CleanupResin (guanidinium thiocyanate) to denature the capsid.
Some protocols seem to use proteinaseK to denature the capsid. (https://www.mdpi.com/2409-9279/1/3/27/pdf-vor)
and some seem intermediate (https://pubmed.ncbi.nlm.nih.gov/29417429/).

Is it very phage dependent? With new hosts do we need to optimize the proteinaseK treatment??

There are 6 B1 phages in phagesdb calling the holin.
