MSSP produces a 2D plot of a single protein descriptor for number of structurally aligned protein chains. From a total of 150 protein descriptors available in MSSP, It is possible to create easily readable and highly informative 2D plots, where X-axis represents the amino acid position in the multiple structural alignment, and Y-axis represents the descriptor's numerical values. The structures can be globally aligned using the different program: MUSTANG [a multiple (protein) structural alignment algorithm] and MAMMOTH-mult (Models Obtained from Theory).

Due to compatibility reasons with the BlueStar Sting Suite, MSSP was originally developed as a Java Applet. However, given that some popular browsers have recently stopped supporting the Java Plugin, we decided to develop a new MSSP version in JavaScript.
