However it fails with non-standard amino acis as far as I know. Then you have to do it manually. These commands could be a good start for your task: http://pymolwiki.org/index.php/Remove http://pymolwiki.org/index.php/Fuse > So I'd like to change FOR- > ACE and ETA-> NH2 > twisely for the 1MAG dtructure hm, shouldn't it be the other way round? FOR is N-terminus and ETA is C-terminus? Cheers, Thomas -- Thomas Holder MPI for Developmental Biology Spemannstr. 35 D-72076 Tübingen |
