Hi all,
While reading a crystallographic paper describing the structure
of an apo-protein and its complex I noticed that
the authors described the space goup as P6122 for the unit cell:
a=141.9, b=143.9, c=380.4 !
Could this be considered as a typo or I'm missing something here!
the requirement for the hexagonal is a = b # C....right?
Another observation in that paper too: the B-factors for the 2.4 A
and 3.2 A structures are 39 and 40?? Does this make sense to anyone??
The last question: In the same paper, for the complex structure R and
Rfree are equal (30%) is that an indication for improper refinement
in these published structure? I'd love to hear your comments on that too.
thanks,
Ibrahim
