Thank you both! I will streak out again.

Hi Debbie, Thank you for your reply. I streaked for single colonies and then did three patch plates. Would it be advisable to streak more?

Best,

Greetings,

I am trying to grow liquid cultures of lysogens to be able to complete the sensitivity assay (11.5). However, when trying to grow up liquid cultures, there is very little bacterial growth, even though I have growth on a patch plate. I am concerned that I will not be able to get a lawn on the petri dishes. Does anyone have any advice?

Thanks,
Beth

Thanks Debbie,

Very helpful. Yes, these would be phages not posted to phagesDB. I appreciate your input!

Greetings,

We were wondering, if we had a surplus number of phage that are not purified, is there a good time or way to preserve those to be processed in the future?

Thank you,

I have a question. In DoobyDoo, Feature 65 (on Phamerator), stop 45445, has some of the features of a RecA, but not all of them. Therefore, I do not believe we should call this a RecA recombinase. On this powerpoint, our cluster (DV), falls under the category of not having a RecA recombinase but calling it anyway. Does this mean that we should not call it a RecA recombinase, or that we should call it a RecA, even though it is not a true RecA recombinase?

Thank you,

Thank you so much to both of you for your help. Very interesting!

Sure, Sorry about that! We are annotating DoobyDoo and the phamerator feature number is 10. The stop codon is 8910.

Greetings,

We are investigating the function of a protein with sequence: MEYMPADLARTLSAMARGTHNEICGFILDDWTLISVRNVAKLPTISFEMSMNAILGAVEMAAASGREILGTYHSHPGGSTEPSETDLHGWPRFIDGSYARYWVVTGDTVREFERTGEGSEIGFQLIHSIGIGVVVKRPEEGMDQSVPEDZ

It belongs to a pham that indicates it is a metalloprotease. BLAST Hits indicate either a tail protein or a metalloprotease. If we look at HHPRED, many hits come as a metalloprotease, but without the HEXXH motif. Rather it has a JAMM/MPN Zinc Binding domain. Should we annotate this as a metalloprotease, even without the HEXXH motif?

Thank you for your assistance!
