Probability that a database contains homeometric peptides. Random peptides were selected from a sequence database of 16.8 million amino acids and searched against the entire database to detect their closest δ-homeometric counterparts. Two tolerance settings where used: the top shows results for a tolerance of 0.5 Da, which models low precision data, the bottom shows results for a tolerance of 0.0075 Da, which models high precision data. The results are shown for random peptides of lengths 7, 14, and 21, and for various numbers of missing cleavages.
