BuildPeptide - Using Phosphorylated and Sulfated Tyrosine


I am trying to build to both phosphorylated and sulfated tyrosine containing peptide squences to use for docking. Unfortunately, I am unable to use the BuildPeptide command to construct these peptides as aI always recieve a Segmentation Fault error. I would appreciate any help. I have been trying to convert the starting fasta sequences: GY[TYR:phosphorylated]EEIA and GY[TYR:sulfated]EEIA without any luck. I have been able to construct the unmodified peptide, GYEEIA, successfully.

On another note, I was curious if I had to be concerned when trying to dock these modified peptides using the FlexPepDock command. Any information would be helpful.

Hi Justin,

Have you figured out how to dock modified peptides using the FlexPepDock command?
