[Chimera-users] Addition of phosphates to PDB structures

If you have exactly the same sequence you can use the "match" command
to align chains, for example to move chain B to align it with chain A
using C-alpha atoms:
match #1:.B at CA #1:.A at CA move chains
A new feature request to align chains with MatchMaker was made 7 months
ago but hasn't been implemented.

> One last question. I tried using the Matchmaker option in Chimera and read the documentation but was unable to find a way to superimpose two molecules (chains) within the same PDB files. I am sure you are aware that a lot of PDB files have more than one structure for the same protein present in the file, whether it be inactive, active, with an inhibitor bound to it or what not... I found that Chimera will only let me match objects in two different PDB files. Is there a straight forward way to do this?

If you do want to ask for opinions on which docking program to use for this purpose, CCL.net may be a suitable forum, or to ask about DOCK in particular, you could post to dock-fans at docking.org
