Phosida

Phosida is a comprehensive bioinformatics tool designed for the analysis and identification of post-translational modifications (PTMs) in proteins. It serves as a crucial resource for researchers in the field of proteomics, enabling the detailed examination of PTMs, which are chemical modifications that occur to proteins after their synthesis. These modifications can alter the function, activity, and localization of proteins, playing a pivotal role in a wide range of biological processes and diseases.

Overview

Phosida allows users to search for specific PTMs, including but not limited to phosphorylation, ubiquitination, and acetylation, across various species. The database integrates information from high-throughput mass spectrometry-based experiments, providing insights into the functional implications of PTMs. By offering a user-friendly interface, Phosida facilitates the exploration of PTM sites, their evolutionary conservation, and the enzymes responsible for their addition or removal, known as kinases and phosphatases for phosphorylation, for example.

Features

• Comprehensive PTM Database: Phosida includes data on thousands of proteins and their associated PTMs, collected from extensive mass spectrometry experiments.
• Cross-Species Comparison: It allows for the comparison of PTM sites across different species, aiding in the understanding of evolutionary conservation and functional significance.
• Enzyme-Substrate Relationships: The tool provides information on potential enzyme-substrate relationships, helping researchers identify the enzymes that may be responsible for specific PTMs.
