Window position representation and comparison of sequence logos between positive and negative sites. a) Position nomenclature that has been used throughout the study. Sequence windows divided into negative (-) and positive (+) sub-windows. In each subwindow, amino acids are numbered in an incrementing order. b) Sequence logo of positive consensus sites indicating preferences in amino acids in each window position. c) Sequence logo of positive non-consensus sites. d) Sequence logo of negative consensus sites. e) Sequence logo of negative non-consensus sites.
