Extended Data Fig. 2: Peptide 15N incorporation rates.
From: Tracking nitrogen allocation to proteome biosynthesis in a marine microbial community
Histogram of 15N incorporation rates from peptide timecourses (gray; total n = 9062) and fitted t-distribution (solid black line) used to determine peptide enrichment thresholds. Using the t-distribution as a null, the false discovery rate for 15N-enriched peptides (incorporation rate >0.898 atom% / h; n = 862) is constrained to 4.76%.
