[ccp4bb] disordered cysteine

2024-04-22 Thread Italo Carugo Oliviero
Dears, is it possible for a cysteine to be conformationally disordered? It seems strange to me. If it were, it would almost certainly be exposed to the solvent and thus easily oxidized irreversibly. Do you perhaps have any information on conformationally disordered cysteines? I thank you, Oliviero

In a few months, I will retire, because my brain thinks it is still young but the rest of the body disagrees and thinks the brain is slightly senile. Of course, I will miss the protein structures very much, so unpredictable in their insolent beauty. I have devoted several years of my life to the

You might try Stride (http://webclu.bio.wzw.tum.de/stride) or 2Struc ( http://2struc.cryst.bbk.ac.uk; which is not available now but was available some time ago). Best, Oliviero Il giorno mer 13 nov 2024 alle ore 16:31 Robbie Joosten < robbie_joos...@hotmail.com> ha scritto: > It is, but it is

Dear Tommi, you could write a program (perhaps with ChatGPT) that (i) stores water molecules, (ii) stores protein atoms, and (iii) searches, among the water molecules, for those that are close to two protein atoms that belong to different chains. Oliviero Il giorno mer 6 nov 2024 alle ore 16:43 Ka

[ccp4bb] IDS in PDB

2025-03-03 Thread Italo Carugo Oliviero
A brief reflection on IDPs Increasingly, people with a computer science background are analyzing the data deposited in the Protein Data Bank. In the case of conformation disorder analyses, they consider residues that are explicitly stated to be disordered (the old REMAR 465 records). This is not
