Protein lysine acetylation plays an important role in the normal functioning of cells, including gene expression regulation, protein stability and metabolism regulation. Although large amounts of lysine acetylation sites have been identified via large-scale mass spectrometry or traditional experimental methods, the lysine (K)-acetyl-transferase (KAT) responsible for the acetylation of a given protein or lysine site remains largely unknown due to the experimental limitations of KAT substrate identification. Hence, the in silico prediction of KAT-specific acetylation sites may provide direction for further experiments. In our previous study, we developed the acetylation set enrichment based (ASEB) computer program to predict which KAT-families are responsible for the acetylation of a given protein or lysine site. In this article, we provide KAT-specific acetylation site prediction as a web service. This web server not only provides the online tool and R package for the method in our previous study, but several useful services are also included, such as the integration of protein-protein interaction information to enhance prediction accuracy.

蛋白质赖氨酸乙酰化在细胞的正常功能中起着重要作用,包括基因表达调控、蛋白质稳定性和代谢调节。尽管通过大规模质谱或传统实验方法已经鉴定出大量的赖氨酸乙酰化位点,但由于 KAT 底物鉴定的实验限制,负责给定蛋白质或赖氨酸位点乙酰化的赖氨酸(K)乙酰转移酶(KAT)在很大程度上仍然未知。因此,KAT 特异性乙酰化位点的计算预测可能为进一步的实验提供方向。在我们之前的研究中,我们开发了基于乙酰化集富集(ASEB)的计算机程序来预测哪些 KAT 家族负责给定蛋白质或赖氨酸位点的乙酰化。在本文中,我们提供了 KAT 特异性乙酰化位点预测的 Web 服务。这个 Web 服务器不仅提供了我们之前研究中方法的在线工具和 R 包,还包括了几个有用的服务,如整合蛋白质-蛋白质相互作用信息以提高预测准确性。该 Web 服务器可免费访问:http://cmbi.bjmu.edu.cn/huac。
