To dephosphorylate GP-9B, an aliquot (50 µl) of the isolated protein sample (see above) was analyzed by LC-ESI/MS before and after incubation with 1 unit of alkaline phosphatase (Sigma, St. | |||||||||||||||

To identify a phosphorylated residue in GP-9B, an aliquot (200 µl) of the protein isolated by ion-exchange and gel filtration chromatography (see above) was dried in a SpeedVac and incubated with 25 µl of 8 M urea in 0.4 M ammonium bicarbonate, 2.3 µl of 100 mM DTT at 50°C for 15 min. | |||||||||||||||

Thus, we conclude that in marked contrast to the hitherto known pheromone-binding proteins, GP-9B undergoes phosphorylation and thus existed in two forms, phosphorylated GP-9B (pGP-9B, observed MM 14,810 Da) and dephosphorylated form (GP-9B, observed MM 14,730 Da). | |||||||||||||||

GP-9B existed in two forms, one of them is phosphorylated. | |||||||||||||||

|
We then reasoned that the difference in the observed and calculated molecular masses could be due to phosphorylation of GP-9B, in addition to formation of disulfide bridges. | |||||||||||||||
