Biochemical Society Transactions is published by Portland Press on behalf of the Biochemical Society. Three Parts of each volume contain the medal lectures and colloquia presented at a meeting of the Biochemical Society or one of its constituent interest groups and, occasionally, the colloquia of other scientific meetings held in the UK or elsewhere; these parts are also available online. Abstracts of posters presented at meetings are published in the three alternate Parts of each Volume, and are only available as accompanying camera-ready supplements.
