So, the "native" , say, space group is
P43 21 2. While collecting the data I processed in P43 21 2
and in P41 21 2. Phaser gave the solution in P43 21 2,
despite I asked it to search for all the space groups within
that point group. Twinning... I would hope there's not... I
could check but since the processing worked so well I was
not expecting such a thing.
Depending on the refinement strategy, I
get mostly R free around 0.36 and R work aroun 0.29-0.30.
But I can also get 0.39 and 0.30, this looks to me more
like a "big gap".
The electron density looks fine to me.
I mean, it is mostly the same structure except for those
mutations.
