Hmm, what are the perfect bonds, angles for NAD in your protein? remember that reactive groups can be in a stressed conformation, compared to ideal in vacuo conformations. As part of their functon. anyway, you'll have to check the restraints definition file (.cif). Bond lengths and angles are

[ccp4bb] crystallization of synthetic peptides

Dear crystallographers, Because of the low cost and speed of synthesizing 40- to 60-mer peptides, I wonder whether anyone has (good or bad) experiences crystalizing such peptides. In literature, I've found up to 34-mer synthetic coiled coils, but no other protein class. I can imagine that a

That's progress! A century ago we'd need an infinite amount of monkeys typing on an infinite amount of typewriters to produce a single paper. Now we need just a finite amount of gamers to produce 7+ models to get one that looks quite like a folded protein. And it saved an heavy atom soak as

How about disorder and/or partial occupancy? B-factors of the Thr and Cl seem pretty high compared to the rest of the structure. Hydrolysis during (possibly weeks/months of) crystallisation is another option. Check the pH and presence of nucleophiles. cheers, Hans Mike Gretes schreef: Hello,
