Fig. 1From: Biogeographic traits of dimethyl sulfide and dimethylsulfoniopropionate cycling in polar oceansThe conceptual sketch of known key proteins and pathways involved in microbial DMS/DMSP cycling. The different catabolic pathways are marked in different colours and distinguished using numbers 1–7. The dotted arrow indicated that a series of enzymatic reactions are required to form the end productBack to article page
