Konu: Re: [Chimera-users] adding residues to N-terminal

Hi Dilara,

In order to enter commands you need to show the Chimera command line, which you can do with the Favorites→Command Line menu item. If you want the command line to show up every time you start Chimera, use Favorites→Add to Favorites/Toolbar… and click the “Auto Start” button for the Command Line in the resulting dialog, then click the Save button.

Good days,

I'm new user of Chimera therefore I need help using build structure option of program.

I want to add MRAE residues to N-terminal of enzyme as an alpha helix structure but I can not use the directions of tutorial such as:

addaa tyr,30 :29.a

- add tyrosine in an extended conformation as residue 30, after residue 29 in chain A (the new residue will also be in chain A)

Where can I write this command?

I'm trying to add four residues to N terminal but I'm adding them to another point. I'm sending the screen image.

Please help me.

Best regards
