Dear Pavel, sorry for the late reply. You might look at the tyrosine-phenol lyase structures, in which a small domain in one of the two crystallographically independent protein subunits is discretely disordered, PDB IDs 6DUR and 6ECG. Actually, modeling the small domain in the two discretely

Crambin (quick search for “Martha Teeter” and “Crambin” should yield dividends)? There are some very high resolution structures of that with multiple conformations. Harry > On 23 Aug 2022, at 23:02, Pavel Afonine wrote: > > Dear community, > > I’m looking for an example of a crystal

Hi Pavel, I guess one which might a very good example for your requirements is Urease from sporosarcina pasteurii. The active side is covered by a “mobile flap” (chain C, residues 320- 340). Depending on the active site bound molecule (substrate analogue, inhibitor, …) the flap can occur in

Dear Pavel, Recently we determined the structure of a fusion protein with 2.5 chains in the AU in P3(2)21 (I posted this case in the ccp4bb). The protein forms a pentamer with one chain sitting on the 2-fold. I refined it in P3(2) with 4 well defined chains and the 5th chain having two

Dear Pavel, One of my colleagues solved this structure ( https://www.rcsb.org/structure/2gn0). I watched in awe while he built and explained the structure. Hopefully the structure is useful -Bharath On Tue, Aug 23, 2022 at 6:03 PM Pavel Afonine wrote: > Dear community, > > > > I’m looking for

Dear community, I’m looking for an example of a crystal structure where a large group of atoms (as large as a whole chain or even a domain) have more than one distinct conformation that would require modeling of such chain/domain as more than one individual copy, with each copy having partial
