Ellen, Historically, we called the capsid maturation protease based on synteny. We would like to have more evidence than that when calling it now. So it depends on which gene and phage genome you are talking about. However, to answer you question generally, if you have the evidence you describe above, you would record exactly what you said for the SIFs, and the function call would be Hypothetical Protein. If you let me know what gene/genome, i could be of greater help. debbie |

Hi Jamie, I would continue to call this a tail terminator for 2 reasons. One, the minor tail protein of lambda that it hits is a tail terminator along with the SPP1 hits. Secondly, it is in the right place for it. I agree, we fall under the threshold of 90% probability, and I usually don't consider anything under 90%, but in this case I think it is a good prediction. |

Fred, I too would be inclined to delete this gene. debbie |

Hi Fred, My recommendation is to not take any one piece of data when making this decision. I believe the best start can most easily be derived from the Starterator report. Take a look. comparative data is always useful. Let me know if you have additional questions. debbie PS There is a lot of biology in the answer to your general question. The ribosome loves to treat the sequence like one big operon, but that isn't what happens. Starts and stops along the way have to do with regulation, most of which falls into the 'I don't know why' category. |

Hi Fred, Thanks. First of all, Heath is a cluster B4 phage. Have you noticed the orange lines that crisscross the B4 genomes in phamerator. Do you know what that is indicating? They are likely some sort of repeats. There are 2 resources to point you to: 1. A paper: Cluster K mycobacteriophages: insights into the evolutionary origins of mycobacteriophage TM4 2. Check out Section 4.2.3.in this doc "Exploring bacteriophage biology". It would be great to look for them! What you don't want to do is include the repeats in your protein calls. In both cases, I would call the genes much shorter than you, mostly to respect the coding potential. For gene 79, I think most of the data fits a start at 63861. For gene 74, I think that most of the data fits a start at 62311. Let me know what you think or if you have additional questions. Please add the forum post (just a link) to your cover letter when you submit this genome. So that the reviewer knows the energy that you invested in the calls. debbie |

Hi Fred, I would need additional info to help evaluate. What is the phage? Would you attach your DNA Master file? Have you looked at Starterator data? debbie |

Hi. I was able to get on a minute ago. Wanna try again? debbie |

Susanne, Yes! The correct way to document your tRNA is found here: https://seaphagesbioinformatics.helpdocsonline.com/documenting-trnas-in-dna-master Good Luck, debbie |

Hi Deb, I knew that the data obtained in PECAAN was static, meaning if you ran the programs on March 2019 and then reviewed on March 2020, the results would be different because the PECAAN data was out-of-date. What I didn't know, or rather didn't quite put together, is that the HHPred databases are downloaded periodically at WKU, allowing all of the programs to run faster. So, Claire Rinehart and colleague, Dex Wood, are actually looking for results such as what you just got to know that the data is discrepant enough to check on database dates. Today Dex found 2 databases out of date and will upload them tonight. When you re-run your HHPred data, the results will change a bit. Good catch! debbie |

Kyle, Yes! Have you made a phage page for Gole? That is the first step. Second step is to email Dan with the request to post the sequence there. Cool! debbie |
