FASTA file containing 75,603 non-redundant peptides sequences. The sequences come from combining XenBase 9.1 Xenopus laevis peptide sequences with the predicted peptide sequences from Wuhr et al. 2014 (https://www.ncbi.nlm.nih.gov/pubmed/24954049 and http://dx.doi.org/10.1016/j.cub.2014.05.044) – M. Wuhr, R.M. Freeman, M. Presler, M.E. Horb, L. Peshkin, S.P. Gygi and M.W. Kirschner, 2014, 'Deep proteomics of the Xenopus laevis egg using an mRNA-derived reference database', Current Biology 24, 1467–1475. The combined dataset was run though the cdhit (https://www.ncbi.nlm.nih.gov/pubmed/23060610) software with a threshold of 95% sequence identity to remove redundant sequences.
