Dear DOCK Blaster users,
We made changes in the sampling schemes ("coarser", "finer") used by DOCK Blaster effective Sept 10, 2009. We expect jobs should run much as they did before the change, but we are performing a thorough study to check our prediction.
Dear DOCK Blaster Users:
We discovered a problem that may have produced strange results for any DOCK Blaster job containing a metalloenzyme - often Zn - coordinated by one or more histidines. This problem was in effect between Aug 28 and Sept 11, 2009 at 4:30pm.
If you started a DOCK Blaster job in that time frame, please discard the previous results and run your new job.
Dear patient ZINC users:
You may have been as puzzled as we were by the nearly 100,000 protonated arylamines in the physiological pH range (6-8) in ZINC as of August 2009. Now whereas the pKa of amines on aryl rings does vary rather over a couple of logs based on the subsitution pattern both on N and the ring itself, it is a good rule of thumb that these compounds are rarely protonated, unless the pH is say 5 or lower.
We have been doing some housekeeping, listed below. When changes are made in ZINC, exported subsets will only be corrected if they were exported after Sept 8, 2009.
= ZINC =
1. We found and fixed 64 ZINC entries with incorrect protonation of triaminopyrimidines.
2. We found 112 ZINC entries with incorrectly protonated arylhydrazines: [NH3+][NH]a. We deleted these completely from ZINC, and have reloaded them, so they now have new ZINC IDs. We regret this, but it was the only practical way.
"Automated docking screens: a feasibility study" has appeared at J Med Chem, ASAP.
Here is the link: http://pubs.acs.org/doi/abs/10.1021/jm9006966
We hope you find it interesting and look forward to discussing with you.
We revoked 12M ZINC compounds from Pubchem this week. We thought you might like to know more about this. If so, read on...
We are holding an automated docking party to celebrate the release of DOCK Blaster on 9/9/9. Free docking for everyone, and some free beer too.
docking.org will be rebooted Friday evening circa 5.30pm - 6.30 pm local time.
Everything will stop cold for up to an hour while we upgrade our equipment.
Thank you for your interest, support, and patience.
The Community Structure Activity Resource at Michigan University starts its first public challenge tonight at midnight. We've already booked our tickets on the bullet train from Tokyo airport so we can be among the first to savor the "PDB nouveau". There will be a session at the spring ACS in San Francisco in 2010 to discuss this. If you want to participate, you need to submit by Oct 5, so don't just sit there.
Please take a look at their website, http://csardock.org/ and see what you think of it.
