Unimod

This FAIRsharing record describes: Unimod is a community-supported, comprehensive database of protein modifications for mass spectrometry applications. The aim is to provide accurate and verifiable values, derived from elemental compositions, for the mass differences introduced by all types of natural and artificial modifications. Other important information includes any mass change, (neutral loss), that occurs during MS/MS analysis, and site specificity, (which residues are susceptible to modification and any constraints on the position of the modification within the protein or peptide).

背景概述

Unimod是一个社区支持的蛋白质修饰知识库，创建于2004年，专注于质谱应用，提供基于元素组成的准确质量差异值，涵盖自然和人工修饰类型，并包括MS/MS分析中的质量变化和位点特异性信息。该数据库涉及生物信息学领域，支持开放访问，但需要用户登录进行数据管理，无版本控制，由日本、英国和美国等国家开发维护。
