debbie	The current position is to call membrane proteins found by DeepTMHMM. https://dtu.biolib.com/DeepTMHMM See the powerpoint at this forum post for current details. https://seaphages.org/forums/topic/5438/ debbie

debbie	Kathleen, I would careful to apply minor tail proteins to small proteins, especially when they are situated in a non-canonical place. Too often, the motifs of capsid proteins and tail proteins can look very similar - too similar to know what it is! debbie

debbie	Alison, Hi. The hit to tail tube protein is what we call "major tail protein". Its place in EC is in the typical position in a genome. As for what should be called a tail tube protein is something that needs further investigation. debbie Edited 06 Apr, 2023 17:30

debbie	Hi Ellen, If you hit a single stranded DNA binding protein downstream of a RecE, it is likely that you have its companion protein, RecT-like DNA pairing protein and I would call it. To learn more about RecE and RecT, reading this paper may help. https://pubmed.ncbi.nlm.nih.gov/18923412/

debbie	Hi all, It is apparent that RefSeq (GenBank records that start out NC_XXx) are not updating with any changes sent to NCBI. Use with caution. debbie

Hi all, I just checked Wizard, and genes 16 (capsid maturation protease), 19 (major capsid hexamer protein) and 20 (Hypotheticall Protein) are all correct at phagesDB, Phamerator and in the Genbank file KU998234. They are disparate in the RefSeq file (NC_030913) at GenBank, BUT we have no control over their updates. Avoid RefSeq files as much as possible, because we cannot update them. Since Phamerator and phagesDB are informed by the same data set, they will always be the same unless you catch them in their updates. As for forums and such, since most folks ask questions when their genome is in draft form, lease ignore the number and refer to a gene by its stop. Currently as we are curate files (for functional calls) that information goes to GenBank first, then those changes are recognized and phamerated. that output is then picked up web Phamerator, phagesdb, starterator and their outputs are then posted. The timing for each program is automated and set differently for each one, but as updates post, the rest is then processed and posted pretty quickly. debbie

debbie	Hi Beth, Before trying anything else, have your students close the program (maybe even restart their computer) and then try again. debbie

debbie	I am willing to call this a head-to-tail stopper because the first hit is to gp20 of L5. while we have not updated the label of that gene, when you HHpred it, it is a good hit to the 5A21_G project, which is the gene that we are assigning the function had-to-tail stopper. debbie

debbie	I would call this the helicase loader. I am not sure of the answer to your questions, but it is in the neighborhood. debbie

Hi Adam, My answer is I don't know. This cluster of genomes is not like the others. It is a podo and I am not sure it fits the canonical features of podos. In order to answer this question, a review of podovirus structures is warranted. What are the canonical featured of them? So a deep dive into the literature is warranted here. Next, the cryoEM data is pouring in to the PDB, so what we have access to now vs when this cluster first appeared has grown. Next, in the literature you can find good reviews about podos and myos tails(and learn that the tail structures of siphos is a bit more elusive). We'll need to apply that to this. Next, your are cherry-picking one gene is a very non-canonical place in the genome. Structural genes frequently hit heads and tails and until we can clearly determine what we have going on here, I recommend that we prudently wait on jumping the gun. Finally, the same terminology doesn't always cross from sipho, myo and podo. So some thought will be required. Keep us posted as you do your investigations. debbie
