The News & Views 'Biochemistry: Origin of a key player in methane biosynthesis' (Nature 543, 49–50; 2017) by Tadhg P. Begley indicated that a paper by Moore et al. (Nature 543, 78–82; 2017) solved an outstanding problem — the biosynthesis of coenzyme F430. However, a paper (K. Zheng et al. Science 354, 339–342; 2016) that solved this problem was published shortly before the work by Moore and colleagues. A corrigendum for the paper by Moore et al. can be found on page 116.
