The sulfolipid sulfoquinovosyldiacylglycerol is present in the
photosynthetic membranes of plants and many photosynthetic bacteria. A
novel gene, sqdX, essential for sulfolipid biosynthesis in
the cyanobacterium Synechococcus sp. strain PCC7942 is
proposed to encode the cyanobacterial sulfolipid synthase catalyzing
the last reaction of the pathway.
