Friends, I am trying to modify the sugar of a nucleotide. I am interested in making a linkage of two carbons in the sugar as in the attached pdb. I tried to use the Build structure -> modify structure option but it does not work in the sense that when i select carbon atom (c2') and tried to connect it to an oxygen, chimera says that it is already bonded and hence some bonds to create a new one. Is there any way to make such linkages as in the pdb ? Thanks, Bala
