Figure 8

Principal component analysis of LEAP class 2, hydrophilins, HSP12, WHy domain and LEAP class 8.

Abbreviations used: Hy: hydrophilins; W: WHy domain; 2: LEAP class 2; 8: LEAP class 8; HSP: HSP12. (i) Physicochemical properties: isoelectric point: pi, FoldIndex: gi, GRAVY: gr, net charge at pH 7: ch, mean hydrophilicity: hi, hydrophobicity (<H>): ho, mean average flexibility: fl, mean bulkiness: bl, mean molar fraction of buried residues: br, mean molar fraction of accessible residues: ac, mean transmembrane tendency: tr, molecular weight/length: ml. (ii) Ratio [(%amino acid X)/(% amino acid X Uniprot)]: pctA.Unip: A, pctC.Unip: C, pctD.Unip: D, pctE.Unip: E, pctF.Unip: F, pctG.Unip: G, pctH.Unip: H, pctI.Unip: I, pctK.Unip: K, pctL.Unip: L, pctM.Unip: M, pctN.Unip: N, pctP.Unip: P, pctQ.Unip: Q, pctR.Unip: R, pctS.Unip: S, pctT.Unip: T, pctV.Unip: V, pctW.Unip: W, pctY.Unip: Y. (iii) Amino acids combination: [D+E]: c1, [K+R]: c2, [D+E+K+R]: c3, [D+E−K−R]: c4, [A+I+L+V]: c5, [F+W+Y]: c6, [N+Q]:c7, [S+T]: c8, [C+W]: c9, [R+E+S+P]: c10, [C+F+W+Y]: c11.
