I thought symexp() would accomplish this, no? From: http://pymol.sourceforge.net/newman/user/S0400xtal.html
Something like: fetch 3hhz symexp mysymm, 3hhz, (3hhz), 2.75 (I came up with 2.75 by trail-and-error as 2.5 generates no symmetry mates and 3.0 generated too many) In the case of 3m2m, the header you pasted shows there are 12 potential biological assemblies, 1 through 8 are all monomeric, however. 9 through 12 are the dimeric assemblies. If you need a dimer, you need to download any one of 9 through 12, which are probably all equivalent to one another. Note that PISA seems to believe that this is a monomer. I would be sure that you have other evidence that this is a dimer, as there are other crystal contacts in the deposited 3m2m. These might also help http://www.pymolwiki.org/index.php/Symexp http://www.pymolwiki.org/index.php/BiologicalUnit -Chad On Mon, Feb 28, 2011 at 12:20, kanika sharma <ksharma...@gmail.com> wrote: > I have a dimeric protein 3HHZ.....to generate the dimer foll transformations > have to be made....the problem is that this is an identity matrix,so will > not change anything...can anyone help with this?? > how can i get the asymmetric unit to generate dimer?? > > REMARK 350 APPLY THE FOLLOWING TO CHAINS: A, B > > REMARK 350 BIOMT1 1 1.000000 0.000000 0.000000 0.00000 > > REMARK 350 BIOMT2 1 0.000000 1.000000 0.000000 0.00000 > > REMARK 350 BIOMT3 1 0.000000 0.000000 1.000000 0.00000 > On Fri, Feb 25, 2011 at 6:40 PM, Hongbo Zhu > <hongbo....@biotec.tu-dresden.de> wrote: >> >> Hi, Kanika, >> >> are you looking for biological units of proteins when you say stable >> dimer?
