Resumen:
It has been reported that higher
plants and cyanobacteria synthesise sucrose (Suc) by a similar sequential action of sucrose-phosphate synthase (SPS) and
sucrose-phosphate phosphatase (SPP). In the genome of the marine unicellular cyanobacterium
Synechococcus sp. PCC 7002 there is a
sequence that was not annotated as a putative SPP encoding gene (sppA), although the sequence was available.
In this study, we do functionally characterise the sppA gene of that strain and also demonstrate that it is cotranscribed
with spsA, the SPS encoding gene.
This is the first report on the coordination of Suc synthesis gene expression
in an oxygenic-photosynthetic organism.
