DiANNA是一种最新的人工神经网络和Web服务器,它可以确定蛋白质的半胱氨酸氧化态和二硫键连接,仅考虑其氨基酸序列。DiANNA 1.0版使用前馈神经网络来确定哪些半胱氨酸参与二硫键,并采用新的架构神经网络来预测哪些半胱氨酸与哪些其他半胱氨酸共价结合。在1.1版的DiANNA,这里描述的,我们通过应用支持向量机与光谱内核的半胱氨酸分类问题,以确定是否半胱氨酸是还原(游离巯基状态),半胱氨酸(参与二硫键)或绑定到金属配体扩展功能。在后一种情况下,DiANNA预测铁,锌,镉和碳之间的配体。请访问:。
DiANNA is a recent state-of-the-art artificial neural network and web server, which determines the cysteine oxidation state and disulfide connectivity of a protein, given only its amino acid sequence. Version 1.0 of DiANNA uses a feed-forward neural network to determine which cysteines are involved in a disulfide bond, and employs a novel architecture neural network to predict which half-cystines are covalently bound to which other half-cystines. In version 1.1 of DiANNA, described here, we extend functionality by applying a support vector machine with spectrum kernel for the cysteine classification problem—to determine whether a cysteine is reduced (free in sulfhydryl state), half-cystine (involved in a disulfide bond) or bound to a metallic ligand. In the latter case, DiANNA predicts the ligand among iron, zinc, cadmium and carbon. Available at: .
