Hello, Hope this email finds you well. I am Satirtha Saha, an undergrad research assistant at UIUC. Currently, I am using ChimeraX for one of my research projects. I need to build structures and download the PDB files. I can do that for all L amino acid containing peptides, but I don’t know how to use ChimeraX for D amino acid containing peptides. For example, I have a sequence NWF. Now it is available in this standard L format and also in NdWF format. As ChimeraX is not case sensitive, I don’t know how I should give the command to build the structure with D amino acid containing peptide. Secondly, I have some peptides that have Amidation or NH2 at the C terminus. I don’t know how to add this to my structure. Please let me know how to solve this to issues. That will be really helpful for me. Have a great day. -- Yours sincerely Satirtha Saha He/Him/His Beloit College | Class of 2025 Triple Major | Biochemistry, Cognitive Science and Data Analytics Research Assistant | Sweedler Lab | UIUC Admissions Ambassador | Office of Admissions, Beloit College Funding Board Member | Beloit Student Government (BSG) +1(608) 473-6615<tel:+16084736615> Schedule an Appointment<https://admissions.beloit.edu/portal/chat?utm_source=www.beloit.edu&utm_medium=referral> sahass@beloit.edu<mailto:sahass@beloit.edu> [Image][cid:image002.png@01D9BB19.9CD8CA10]
