Welcome to POTAMOS

Post-Translational Modifications (POTAMOS) Mass Spectrometry Calculator is a free web application that simplifies mass spectrometry calculations for post-translationally modified proteins. It consists of three interacting parts:

For more details on each part, please refer to the Manual.

An example of the usage of POTAMOS:
Calculation of mass and charge of a modified oligopeptidic sequence of an H3 histone protein (left). The respective structure (right) was produced by VMD and it is based on the PDB structure of HP1 bound to H3 histone (code: 1KNE). Only the H3 oligopeptide is shown.

This application was developed by A. Vlachopanos (T.E.I. of Epirus).
