Posttranslational modification (PTM) is an important biological mechanism to promote functional diversity among the proteins. So far, a wide range of PTMs has been identified. Among them, glycation is considered as one of the most important PTMs. Glycation is associated with different neurological disorders including Parkinson and Alzheimer. It is also shown to be responsible for different diseases, including vascular complications of diabetes mellitus. Despite all the efforts have been made so far, the prediction performance of glycation sites using computational methods remains limited. Here we present a newly developed machine learning tool called iProtGly-SS that utilizes sequential and structural information as well as Support Vector Machine (SVM) classifier to enhance lysine glycation site prediction accuracy. The performance of iProtGly-SS was investigated using the three most popular benchmarks used for this task. Our results demonstrate that iProtGly-SS is able to achieve 81.61%, 93.62%, and 92.95% prediction accuracies on these benchmarks, which are significantly better than those results reported in the previous studies. iProtGly-SS is implemented as a web-based tool which is publicly available at http://brl.uiu.ac.bd/iprotgly-ss/ .
翻译后修饰(PTM)是促进蛋白质功能多样性的重要生物学机制。到目前为止,已经鉴定出了多种翻译后修饰。其中,糖基化被认为是最重要的翻译后修饰之一。糖基化与包括帕金森病和阿尔茨海默病在内的不同神经疾病有关。它还被证明与包括糖尿病血管并发症在内的多种疾病有关。尽管到目前为止已经做出了所有努力,但使用计算方法预测糖基化位点的性能仍然有限。在这里,我们展示了一种新开发的机器学习工具,称为iProtGly-SS,它利用序列和结构信息以及支持向量机(SVM)分类器来提高赖氨酸糖基化位点预测的准确性。使用用于此任务的三个最流行的基准对iProtGly-SS的性能进行了研究。我们的结果表明,iProtGly-SS在这些基准上能够实现81.61%、93.62%和92.95%的预测准确率,这明显优于先前研究报告的结果。iProtGly-SS作为基于网络的工具实现,可在http://brl.uiu.ac.bd/iprotgly-ss/上公开获取。
