Extended Data Fig. 4: 15N incorporation and data quantity.
From: Tracking nitrogen allocation to proteome biosynthesis in a marine microbial community
(A) and (B) Taxonomic composition of 15N-enriched peptides in each N amendment, characterized by either MS/MS spectra (A) or MS1 signal intensity (B) associated with detected 15N-enriched peptides. (C) and (D) Relationship between 15N incorporation rate and quantity of MS data for peptide timecourses (n = 9062), expressed as either total MS/MS spectra (C) or total MS1 signal intensity (D). Dotted and dashed horizonal lines indicate the lower bound of incorporation rate for 15N-enriched peptides and the upper bound for non-enriched peptides, respectively; intermediate peptides fall in between the two lines. Datapoints are colored by taxon as in (A) and (B).
