Types of substrate ubiquitylation. Mono-, multimono- and polyubiquitylation is presented. Different types of polyubiquitin chains: linked through specific but the same lysine throughout the chain (homogenous chains), linked through N-terminal methionine (linear chains), linked through alternative lysines (heterogenous chains) and chains with one of the chain’s ubiquitin modified by two further ubiquitins linked through different lysines (branched chains).
