[ccp4bb] protein induced precipitation of proteins?

2007-12-03 Thread Jerry McCully
Dear All, Recently I was trying to crystallize a complex of two proteins(40kD vs 20kD). TO my surprise, precipitates immediately appeared in the solution even when I mixed these two proteins at about 1mg/ml. However, the individual proteins were just soluble and stable in the same

[ccp4bb] how to change a membrane protein into a water soluble protein?

2007-12-03 Thread Daniel Jin
Hi, I am wondering whether there is a way to turn a membrane protein with known crystal structure into a water soluble protein by systematic mutagenesis. I guess it should be doable if we introduce enough hydrophilic residues on the surface. Has anyone tested this crazy idea before? Thank

Hi all, has anyone sorted out how to get ciftr running? pdb_extract nicely bundles the information from the pdb header and additional information from the supplementary file (data_template.text, for instance) and writes it into the a cif file. CIFTr, however, does not re-translate lots of

Dear All: Thanks a lot for the prompt replies. The following are the good ideas I have got so far besides some details that I forgot to mention earlier. I tried 10 buffers from pH5 to pH9.0 at 5mM with a final protein concentration of 0.5mg/ml to 1mg/ml. And I also tried to add 0.1M NaCl at
