[Chimera-users] Curiosity regarding amino acid category in UCSF chimera

Hi, In UCSF chimera, when I go to Select > Residue > Amino Acid Category > Hydrophobic, the LYSINE residues also get selected. However, according to the Kyte-Dolittle scale, LYSINE is a fairly hydrophilic residue. Is there any specific reason why chimera lists them as hydrophobic residues? -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016
