Fig. 2: RNA-SIP and lipid-SIP targeting catabolic archaeal protein degraders.
From: Catabolic protein degradation in marine sediments confined to distinct archaea
Relative abundance of 16S rRNA gene sequences of active archaeal protein degraders in total archaea from RNA-SIP gradient fractions in the Helgoland mud (a) and Cumberland Bay (b) sediment incubations. Active archaeal groups were identified based on the subtraction criteria (see Methods; Fig. S1) (c) δ13C values of phytane and biphytane 0 in sediment incubations (n = 2, error bar = SD). Phytane originates from archaeal diether lipids, mostly archaeol, and biphytane 0 from tetraether lipids, dominantly caldarchaeol.
