I have a dimeric protein 3HHZ.to generate the dimer foll transformations have to be madethe 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

my protein is 3m2m..iv downloaded the biological assembly 1 for this.. http://www.rcsb.org/pdb/explore/explore.do?structureId=3M2M to generate dimer for this the BIOMT data is like this from the pdb filei dont know how will this work if its an identity matrix.. REMARK 350 BIOMOLECULE: 1

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 symexp data may not always be consistent with the biomt transformations..although they turn out to be.. considering the case of 3hh7...the biological unit and asymm unit are same...to form a dimer of this protein...i cannot find a clue by biomt data REMARK 350 APPLY THE FOLLOWING TO CHAINS:

Hi Chad, Kanika, Symexp is for generating symmetry mates, not for (re)constructing biological assemblies. If the BIOMT record gives an identity matrix, it means that there is no further information for building a biological unit. The biological unit is most likely contained in the PDB file. Note

Hi, Kanika, are you looking for biological units of proteins when you say stable dimer? If this is the case, I recommend the page: http://pdbwiki.org/index.php/Biological_unit at the bottom of the page you can find four very useful servers for the determination of biological units of proteins
