Missing carbon group in Tryptophan in protein structure prediction?

26 September 2023 1 10K Report

I predicted a protein structure using trRosetta. I couldn't do homology modeling as no homologs are present. the model contains tryptophan but the indol group of tryptophan lacks one carbon. ( please see the attached image of the structure)

how to cater for it. as I want to perform MD simulation

You can replace this Trp to another Trp in Chimera to get the full structure or even you can create the carbon atom at this position.
