PeptideDB

PeptideDB database assembles all naturally occurring signalling peptides from animal source, which are derived by cleavage from prepropeptide precursor proteins. It includes Cytokine and growth factor, Peptide hormones, Antimicrobial peptides, Toxins and venom peptides, and Antifreeze proteins. PeptideDB database (version 1.0, 2008-04-25) consists of 20,027 peptides from 19,438 precursor proteins covering 2,820 metazoan species belonging to 373 peptide families in total.PeptideDB数据库汇集了所有来自动物源的天然信号肽（signalling peptides），此类肽均由前原肽（prepropeptide）前体蛋白经蛋白酶解切割衍生而来。该数据库涵盖细胞因子与生长因子、肽类激素、抗菌肽、毒素与毒液肽以及抗冻蛋白。PeptideDB数据库（版本1.0，发布于2008年4月25日）总计包含源自19438条前体蛋白的20027条肽序列，涵盖373个肽家族，覆盖2820种后生动物（metazoan）物种。
