Calling all Crystallographers, Please Help! RE: Refining two different covalent species at the same position. I have a protein that is a homo-tetramer ABCD with two symmetrical active sites sitting on a two-fold axis that runs through the AB/CD interface (space group P21212). We developed an in

[ccp4bb] Advice on Enzyme Kinetics (substrate bound plate format)

2012-08-10 Thread Stephen Connelly
I am looking for some expert advice on enzyme kinetics but for an assay in plate format which has the substrate bound. This is different that the usual homogeneous plate assays or heterogeneous assays where the enzyme (catalyst) is plate bound. In short I am trying to look at the Ki of a compo
