Hi Jordan, If I were calling this genome, I would label both of these proteins as membrane proteins. Neither are great matches to known holins, phages can have more than one holin, and while I may not know which one is a holin, I am confident that they are both membrane proteins. If you are compelled to call a holin, 32 is in a 'more canonical' place. Historically, we called the small protein after lysin A the holin. Now that we are moving away from relying on the location as the sole reason for calling a holin, I am most willing to call these proteins 'membrane proteins'. (Because I can't tell which is the holin, although they both may be holins.) The best writing about holins is from Ry Young, Texas A&M. I don't know if there is a definitive article that he has written that helps, becuase he has written a lot. I kinda liked his J Mol Microbiol, Biotechnol (2002) paper, "Bacteriophage Holins: Deadly Diversity". debbie

debbie	Iain, This is all up to GenBank. They have many folks working through the submissions and they get assigned in ways not know to us. I have files posted in 1 day and I have seen them posted 6 months later. debbie

debbie	Hi! Yes, ArV1 is the phage of that paper. Why do you say that AR phages are siphoviridae? debbie

debbie	Amy, I am the one QCing this genome and I have not gotten to it yet. Welkin, would you respond to the intron question? I think that info that may be helpful is found here https://seaphages.org/forums/topic/4926/?page=1#post-7336 Thanks, debbie Edited 03 Oct, 2019 17:06

Hi all, Recently Krista Freeman, a post doc in the Hatfull lab, and Julia Kovalski, an undergrad designed primers for 60 cluster/subclusters of mycobacteriophages. These primers were designed for verification of phage lysates in the Hatfull lab (and not to prematurely assign cluster designations to unsequenced phages). Attached is an Excel sheet of the primers/phages. Krista thought having the fasta files of the phages would be helpful. I thought adding a picture of Julia and Krista would be fun!

debbie	A lot of Cluster EA1s have a tRNA in the middle of a middle tail gene. since you can only call one or the other, call the minor tail gene!

If one looks at the immunity repressor of Cluster F1s like Mycobacteriophage Strokeseat, the coding potential data is confusing. The Starterator data clearly shows only 1 start that is found in all pham members. The start in Strokeseat is at position 34251 (stop is at 33682).(gene length is 570bp). This then provides adequate (just barely) space for promoters for this gene (CRO) and the next one (because they are transcribed in opposite directions). The start of this gene is at 34358 (stop is at 34651). Hope you find this helpful! Unfortunately, as is the nature of Cluster F1s, not all F1s have these phams. Edited 08 Aug, 2023 13:20 152Kb
