Dear Jacob, We recently solved crystal structures of apo and ligand bound forms of a cofactor S-adenosyl-methionine (SAM) dependent methyltransferase RlmJ (http://nar.oxfordjournals.org/content/41/20/9537.long). Comparison of the structures revealed that binding of the cofactor and a substrate

Re: [ccp4bb] unusually low B-factors

I think it may well be a problem with the scaling. It is hard to get a reasonable estimate of the Wilson B at 3A - especially in a small cell. Look at the Log Graph plots - one associated with R factor gives you Fobs and Fcalc v resolution. They SHOULD overlap pretty well, but sometimes they dont

Jacob, Many enzymes do this, not quite as dramatic as calmodulin, but especially hexokinase, and this is important because it was the origin of Koshland's induced fit idea. Glycogen phosphorylase, aspartate transcarbamylase, and phosphofructokinase also do radical things involving subunit

Dear CCP4 community - In case anyone missed this, one interesting example of large conformational changes associated with ligand binding event(s) is T7 RNA polymerase, involved in the initiation, elongation and termination of mRNA synthesis following promoter recognition. Tom Steitz' review from
