Hi Shallee, Rick Pollenz is looking at transmembrane proteins associated with the lysin genes. He may have more insight. Though I am not an expert, it is my understanding that our lysin Bs 'contain' the analogous spanin function of the enteric bacteriophages. So we have avoided using 'spanin' in lieu of lysin B. with the difference in cell walls we would want to be careful that are calls do not cause confusion. You are welcome to deep dive this topic! debbie Edited 23 May, 2024 20:29

debbie	Ping, I can verify that it is down. If it isn't back by tomorrow, i will contact the folks at GeneMark. debbie

debbie	Hi Dane, From the HHPred results, because of the limited nature of the hits, i would not call anything at this time. best, debbie

debbie	Alison and your students, Thank you for your awesome work on this. Maria Gainey presented this and her similar protein at our SMART meeting today and a discussion ensued. For now, we recommend that you call this protein "cyclic nucleotide inhibitor". best, debbie

debbie	Hi Nikki, Sorry to id the paper as Tweety, when the data is about Fruitloop. Bit I di have the paper right! (Just what you needed, more confusion.) I think your decision is a good as we can get at this point. best, debbie

debbie	Be careful what you say about Fruitloop. Go to the paper and see the mas spec table and the map there. (when I looked, the paper doesn't match the GB file). There is a gene in there that you do want to call. i just don't have time right now to match it correctly. Let's touch base before you submit. best, debbie

debbie	Hi Nikki, Mycobacteriophage Tweety has a paper that includes mass spec data. While the integrase and repressor have less sequence homology, that space in between may have enough similarity that you can draw some inferences that are applicable. Let me know what you think. https://onlinelibrary.wiley.com/doi/full/10.1111/mmi.13946 Best, debbie Edited 03 May, 2024 16:22

debbie	Hi Dane, See the attached picture for why I would call a lot of theses proteins membrane proteins and not holins….. yet. Too many to choose from? debbie 392Kb

Hi Fernando, I think I want to stick with what is written in the Cluster O paper. There are 4 transmembrane proteins in the region downstream of lysin A and lysin B. I would call the 4 genes that hit Deep TMHMM transmembrane proteins - membrane proteins. Deep TMHMM is now the preferred method for transmembrane detection. (See Bioinformatics Guide.) And check out that data on phamerator!!! As to why holins may not be detected in HHPRed, I think that list could include that holins demonstrate a lot of diversity, holin activity may need more than one gene, holins are small proteins and must not be easy to crytallize and study. It is not uncommon to not find a hit to a holin. Best, debbie
