The most likely reason is a database version sync. There was a database update to version 256 late yesterday, the wustl website is still showing the results from version 255. The new database is being worked on by Starterator but there are approximately 15 thousand reports it just takes time, I expect all the runs to be completed in a couple more hours. If you still have trouble after the update is posted then please post a specific example or two of exactly which genes and pham numbers are giving you issues and I will investigate further.

It appears from your picture that you are still running an older version of Starterator. The newer version does not crash. Updating starterator is non-trivial which is one of the reasons we went with online reports. I have posted a whole phage report for phage Zolita which you can download. If you want to try to update, I can help you with that just post a followup or email me directly (address is my last name @ wustl.edu).

To update the database use Phamerator, just start up Phamerator, then wait for the download and install. Once Phamerator is done updating Starterator should find phage Skippy. As for "Unphamerator phage", Starterator works much better if you add the Profile in addition to the fasta file. This file gives the locations of all the genes so Starterator does not need to try and figure it out. This file is generated by opening the DNA Master file for the phage and using the default settings of the Genome -> Profile… menu to create and save a .csv file. Transfer that file to your machine running Starterator and use it for the Profile. Finally, all starterator reports are now available online if you don't want to hassle with the whole phage report. They can be accessed from the phagesdb web page for the gene. Here is an example for skippy gene 1: https://phagesdb.org/genes/SKIPPY_DRAFT_1/ On that page is a link to the most recent Starterator Report (currently pham 6729).

cdshaffer	The most recent version of the database, which includes pham 60238 is now posted so you should be good to go.

This gene from phage Hiyaa, currently gene 75 (originally draft gene 78 ) starting at base 55288 (pham 21467) shows more than 25 HHpred hits with 100% probability and 96 to 98% coverage to adenylosuccinate lyase. Here is a link to the PDB entry for 2PFM the second best HHPRED hit to this gene. A very similar protein also in pham 21467 is gene 36 from Gordonia phage Ghobes, this gene also has the annotation of "adenylosuccinate lyase". According to KEGG, one of the primary roles for adenylosuccinate lyase (4.3.2.2) is purine biosynthesis in which it is the second of two enzymes used to convert IMP to AMP. The first step in this pathway is "adenylosuccinate synthetase, PurA-like" which is already an approved sea-phages term. These results would suggest (keeping the nomenclature parallel) adding "adenylosuccinate lyase, PurB-like" Edited 05 Oct, 2018 14:40

cdshaffer	Sally had this error and solved it by deleting all projects; see the last couple of posts in this thread: https://seaphages.org/forums/topic/17/?page=8

Annotation of phage Gilgamesh, gene 43 (27658-28101) in PECAAN. This prediction shows 99.4% prob, with ~90% query and subject coverage HHPRED hit to MutT/NUDIX type nucleotide pyrophosphohydrolase. There is an approved term for "MazG-like nucleotide pyrophosphohydrolase". According to this paper (The Journal of Biological Chemistry 286, 30691-30705) the nucleotide pyrophosphohydrolases fall into "structurally different superfamilies, such as the MutT-related hydrolases (Nudix) (α + β), dUTPase (all-β), dITPase (Maf/HAM1) (α/β), all-α-NTP pyrophosphatases (MazG), and phospho-ribosyl-ATP pyrophosphatase (HisE)." The MazG type are a superfamily made up of all alpha helices as can been seen in this PDB crystal structure of the eponymous MazG protein 3CRA. The MutT (also called Nudix type) show a kind of sandwich with a beta sheet between alpha helices like 4KYX I would propose adding either "MutT-like nucleotide pyrophosphohydrolase" to keep a parallel structure to the other entry or just have a generic "nucleotide pyrophosphohydrolase" at the bottom of the list for those enzymes that are not in the MazG superfamily.

To answer your question on Fe+2 binding, I could not find any in vivo studies but this result is a crystal of an "iron soaked" version of the protein complete with Iron bound as expected and a discussion of the conserved Asp channels that could allow ions to flow into the cavity. I agree on every single point you made. I really don't think there is a good annotation here. I think maybe the best option here is "do no harm" so we will proceed with Yaboi and annotate this gene NKF. We can always change it later.

cdshaffer	DNA processing protein A is on the list, it is officially: DprA-like DNA processing chain A two rows below the red Ku in the second column

cdshaffer	For me when the top of the "add a gene window" is cut off it is because I have the zoom level set to magnify the page. This happens a lot as I typically have my pages default to 150% zoom or so. The tiny 3-line menu in the top right corner can be used to see and or change the current zoom level.
