Nancy,
Hi. Your preferences are not set correctly. The NCBI servers are not available to us anymore. Check Setting Preferences in the on-line Bioinformatics Guide, #2. Click the box and the password needed is Hatfull. You may want to check all of the preference settings while you are at it.

Fernando,
Hi. Did you get this issue resolved. If not, please send me your file.
Thanks,

Susan,
Hi! Start by updating your DNA Master. The current version is 5.23.3 Build 2639 from November 6, 2019.
So the exact dates escape me, but the reason (I think) your version may not be working is that you do not have DNA Master pointing to the right servers. We have Glimmer and GeneMark running on our own servers. Go to 'Setting your Preferences' in the Bioinformatics Guide to check.
If you still are having problems, there are more options.

Steve,
Excellent question, because we simply do not know. But yes, at this time, you can apply it generally!

Dana,
Thanks for the heads-up. This periodically happens due to the way GeneMark makes this available. It is corrected. Your auto-annotation should now include Glimmer and GeneMark calls.

Here is what I know so far. A slippery sequence could not be found in the original EA1 and EA2 annotations. We have looked at EA1 - EA8 annotations so far. Slippery sequences have been annotated in Subclusters EA3,EA4,EA5,and EA6, not in Subclusters EA1, EA2, EA7, and EA8. So if you can find a canonical sequence for the slippage, i would recommend calling it. if you can't, then don't.

There are 2 overlapping open reading frames that can show up in your auto-annotations that are ~ the same size somewhere in the vicinity of bp 22,200. One is a HHpred hit to a helicase (difficult to differentiate further, for now). The other does not have significant hits to anything. Be careful to pick the right one. (There are incorrect calls in the database - to be correct.) An example of a good call is Wayne gp29.

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".
