2.A.2.3.15
Probable sulfoquinovose importer of 467 aas and 12 TMSs (Denger et al. 2014). Sulphoquinovose (SQ, 6-deoxy-6-sulphoglucose) is the polar headgroup of the plant sulpholipid in the photosynthetic membranes of all higher plants, mosses, ferns, algae, most photosynthetic bacteria, and some non-photosynthetic bacteria. It is part of the surface layer of some Archaea. The estimated annual production of SQ is 10,000,000,000 tonnes (10 petagrams) (Denger et al. 2014).
