You may as well have fun by manually building your molecule B into 1.9A ed map
when R-factors are already in mid 30s.

Dear all
Thanks again for more input to the question. And credits to Eleanor and Kay
for pointing out the high R-factor and possible issue with the space group.
Their advice prompted me to revisit the MR solution and it happens that
another solution, in P3121, gave a better map with R-factor
Hi Sam.
If you still have any of your crystals or any protein solution left in the well
you harvested your crystals, I would run a MS/MS with them. Next step would be
to run AF with your known chain A and your best Mass Spec hit (s), and use the
resulting model for MR.
Good luck

Hi,
If you still have crystals left, you could soak crystals with KI3 and collect
data at Cu wavelength for SAD phasing, which could help you to resolve the
missing piece. Maybe.

Yes. I tried to weight those B values by occupancies, but the result is
still not the same as the value reported by refmac5.

I tried both and none of them is the same as reported by refmac5.

Thanks for your reply. Does the refmac5 program weight the mean B value by
the resolution?

Hi Sam,
What you write does not sound good to me.
Did you have Phaser check "all possible [spacegroups] in same pointgroup" (this
is how it is called in ccp4i)? P321 is quite rare, compared to P3121 and P3221.
If you miss a screw axis, you will not find a solution.
An R-factor of 50% does not
12 matches
