Activity and metal content of Rockwell-pMMO in nanodiscs. a 13C methane oxidation activity of Rockwell-pMMO in membranes and in nanodiscs (ND) without or with copper supplementation. Values are shown in nmol 13C methanol•mg−1 protein•min−1. Error bars represent standard deviation of individual measurements (black dots) of n = 6, 3, and 5, respectively. b Copper equivalents per pMMO protomer for Rockwell-pMMO in membranes and in nanodiscs without or with copper supplementation. Error bars represent standard deviation of individual measurements (black dots) of n = 3, 4, and 5, respectively. Source data are provided as a Source Data file
