The MIBiG repository now holds over 2500 entries of experimentally validated BGCs, collected over three iterations of community annotation hackathons with more than 250 participating contributors . This makes MIBiG the largest collection of experimentally characterized BGCs and a variety of downstream tools utilize it as reference dataset . MIBiG is under continuous development and is, at the time of writing, undergoing the fourth round of community annotation hackathons. Besides experimental evidence connecting the BGC to its product, MIBiG also stores additional supplementary information, such as information about functions of genes constituting the BGC.
