Partial amino acid sequence of fructose-1,6-bisphosphatase from the blue-green algae Synechococcus leopoliensis.
Purified fructose-1,6-bisphosphatase from the cyanobacterium Synechococcus leopoliensis was S-carboxymethylated and cleaved with trypsin. The resulting peptides were purified by reversed-phase high performance liquid chromatography and the amino acid sequence of six of the purified peptides was determined by gas-phase microsequencing. The results revealed sequence homology with other fructose-1,6-bisphosphatases. The obtained sequence data provides information required for the design of oligonucleotide hybridization probes to screen existing libraries of cyanobacterial DNA. The determination of the amino acid sequence of cyanobacterial proteins may yield important information with respect to the endosymbiotic theory of evolution.
