MSA and periodicity search by Fourier transform using REPPER FTwin support 11-residue repeat
{"Image DocumentName": "MSA and periodicity search by Fourier transform using REPPER FTwin support 11-residue repeat", "Image ImageDescription": "This multiple sequence alignment of the dimerization regions of b and b\u2019 sequences shows the 11-residue hendecad repeat, with small alanine residues (highlighted in orange) quite common in a and h positions, and larger hydrophobic residue in d and e positions (green). FT analyses of the sequences in the alignment using various scoring matrices confirms the predominant periodicity of the sequences as 3.68 (11/3) as expected for a RHCC. For a left-handed coiled coil the periodicity would be 3.5 (7/2) Peak periodicity is at 3.68 (11 residues/3 turns of helix, right-handed) Left-handed periodicity would be 3.5 (7 residues/2 turns of helix)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
