Dear freinds
We have crystallized a cyanobacterial phycoerythrin which having two (alpha
subunit) in an assymetric unit and held together by only three hydrogen bonds.
When we compare the A and B molecule the RMSD is 1.32. because they same
sequences then how it is possible to that two molecules are deviated at such
extent. now the question is
are both the molecules are crystallographic dimer?
are two molecules are structural subunit as alpha 1 and alpha2?
Is there any problem in refinement ? The structure was refined at 2.6 A with R
0.23/0.28
I hope a possible suggestion
with warm regards
Have a nice day......
