Dear Chimera Thank you for taking the time to answer my question the other day. I also apologize for contacting you outside of business hours due to the time difference. I'm Kenji Matsui, a second-year master's student at a national university in Japan. I have shown hydrophobic interactions between ligands and amino acid residues, how should I display them? I refer to these methods. But, I did not know where to find Examine residues. Therefore, could you please tell me the location of Examine residues? If possible, we would appreciate it if you could attach a diagram after the operation so that we can confirm the operating procedure. *A:Find hydrophobic interactions* Select >> Residue(s) (either in entire structure or within a selected set (see above $ or %)) >> Amino acid category >> hydrophobic >> Action >> Atoms/Bonds >> Show >> Examine residues >> Mouse over atoms or Left click on them to identify them --------------------------------------------------------------------------- 松井 健治 東京農工大学大学院 工学府産業技術専攻 修士 2年 〒184-8588 東京都小金井市中町2-24-16 Kenji Matsui Graduate School of Tokyo University of Agriculture and Technology M2 2-24-16, Nakamachi, Koganei-shi, Tokyo 184-8588, Japan Mail: s214903z@st.go.tuat.ac.jp
