Sedoheptulose-l,7-bisphosphatase

We have isolated and sequenced cDNAs for wheat phosphoribulokinase (PRK), for chloroplast fructose-1, 6-bisphosphatase (FBP) and for both the chloroplast and cj osolic versions of phosphoglycerate kinase (PGK). We are at present sequencing a putative cDNA clone for sedoheptulose-l,7-bisphosphatase (SBP) and isolating the coding sequence of cytosolic FBP. For the sake of comparison, we have also sequenced the E coU gene for FBP (3). 

Chloroplast and cytosolic Fructose-1,6-bisphosphatase (FbPase) and Sedoheptulose-l,7-bisphosphatase (SBPase) have been investigated mainly from spinach leaves (1,2,3). We present data which show significant differences for these enzymes from pea leaves.
