Expression in metaproteomes of methylotrophy related proteins among representatives from all of the clades predicted based on genome annotation to be capable of growth on C1 compounds, in particular methanol. Data is presented as %NSAF values, indicating the proportion of all protein in a sample. Data previously published in refs. [8, 9, 17, 35, 43]. Gene annotations to the left are first Pfam annotation, then Prokka annotation, separated by underscores "____"
