Fig. 4: Overview of key DMSP biosynthesis enzymes and pathways and their environmental importance.
From: Alternative dimethylsulfoniopropionate biosynthesis enzymes in diverse and abundant microorganisms
a, Key DMSP synthesis and cleavage pathways are indicated with known algal and bacterial S-methyltransferases. b, The relative abundance of DMSP synthesis genes and transcripts in SRF, DCM and MES water layers from OM-RGC_V2 (0.22–3 µm size fraction) and MATOU (0.8–2,000 µm size fraction) datasets. c, Clades and taxonomy of DSYE sequences detected in MATOU datasets. The genes in OM-RGC_V2 and MATOU datasets were normalized to recA and β-actin genes, respectively. The size of the pie charts represents the gene relative abundance in the corresponding datasets. Note, no dsyG/dsyGD sequences were detected. CCN, cloud condensation nuclei. MetaG, metagenomes data; MetaT, metatranscriptomes data; RA, relative abundance. SMM, S-methylmethionine.
