Extended Data Fig. 10: Turnover of cytoskeletal proteins in Isochrysidales.
From: Tracking nitrogen allocation to proteome biosynthesis in a marine microbial community
Incorporation of 15N (solid lines) and relative abundance change (dashed lines) into four cytoskeleton (actin/tubulin) peptides of Isochrysidales (coccolithophorids) during the day/dusk and night/dawn ammonium-amended incubations. That 15N incorporation is observed despite a decline in abundance of these peptides suggests these proteins are turned over rapidly, likely as part of cytoskeletal remodeling during coccolith export to the cell surface.
