Kathleen, Yep. It is rule based on a small data set from some mass spec data. Choose the second one. debbie |

I agree with Steve. This may be one of the only places where I rely on that particluar pFam hit. debbie |

Hi Sally, I think I can call a toxin or antitoxin without its partner because the host may carry it. Curious if others agree. debbie |

Vicky, Yes, the hierarchy of what to believe is convoluted. We got tail assembly chaperone calls wrong in this cluster. So Blast data - whether at ncbi or phagesdb - will just regurgitate what we got wrong. BUT, if we got it correct, it would be a good source of info. We are steadily working at correcting the 'wrongs', but it just takes time. debbie |

Shima, What you need to provide is one best explanation for each gene call. Since i don't use PECAAN this way, I can't answer your question. You are correct, Claire set up PECAAN so there is an output that works. But whatever you pick, be sure to identify the problem areas and the thinking process. debbie |

There is another string of forum posts in the cluster specific annotation tips. I just looked at a set of these genes (see the post) and I am worried that the wrong genes are being implicated. Use your phage's HHpred data to make your decisions. https://seaphages.org/forums/topic/5009/ Best, debbie |

Hi Vicky, Here is my 2 cents. I don't think that gene 21 and 22 are tail assembly chaperones. Using the HHPred info in PECAAN. Gene 21 (16902 - 1722 ![]() Gene 22 (17225 - 17635) Significantly hits minor capsid genes, and tail genes. In particular it hits HK07-gp10. That phage was well studied at Pitt and those researchers did not know the function of gp10, so it too is a hypothetical protein, Gene 23 (17682-18221) DOES have a significant hit to a tail assembly chaperone (pfam hit). BUT it is in the right place, so I would consider it. This is my first pass on this. If you read the Cluster specific annotation tip on this subject, you can see others have struggled with this also. https://seaphages.org/forums/topic/5009/ Next step, please run all HHpred at HHPred. IGNORE ALL PREVIOUS SEA-PHAGES ANNOTATIONS. When this first of this Cluster (CloverMinnie and Sour) we thought the TAC HAD TO BE THERE. We now know that is not true. As you re-evaluate this, let me know if you need additional help. Good luck! debbie |

The paper about the queuosine pathway found in Rosebush was published in 2019. I was hoping to have curated those phams and gotten it recorded in phamerator in a better way, but that curation is lagging further behind the data than hoped for. The paper contains the empirical bench data that we want to capture in our annotation. So while others could interpret bioinformatic hits diferently, Rosebush genes have empirical bench data to support the calls. Once the paper was published, Dr. Hatfull and I carefully chose the names to call the genes. They are recorded in the case study that I mentioned. A few minutes ago, I sat down with Christian and he updated the annotation of Rosebush in phamerator for the gene names of the first 6 genes. The processing will take a bit of time, and then the data will have to be transferred to the web version. BUT, in a few hours Rosebush will reflect the correct gene functions for these genes. In the meantime, follow the "Gene assignment as per approved function list" in the table about Rosebush in the aforementioned case study. Sorry for the confusion. debbie |

Hi Erin, Did you check out the case study in the Bioinformatics Guide? https://seaphagesbioinformatics.helpdocsonline.com/article-1596481355 I can't quite answer a general question, but if you give me the specifics, I can try to help. Thanks, debbie |

And the second thing to so do is to make sure you are running as Adminisitrator when you update. best, debbie |
