Tyrosylprotein Sulfotransferase 1, EC 18.104.22.168, TPST-1, Transport And Golgi Organization 13 Homolog A (Drosophila), Transport And Golgi Organization 13 Homolog A, Tyrosylprotein Sulfotransferase-1, TANGO13A.
Tyrosylprotein Sulfotransferase 1, also known as TPST1 is the enzyme which catalyzes the sulfation reaction of protein tyrosines, a post-translational modification of proteins. TPST1 belongs to the protein sulfotransferase family. In addition, TPST1 utilizes 3'-Phosphoadenosine-5'-phosphosulfate (PAPS) as the sulfonate donor and also binds proteins with target tyrosine residues to eventually form the tyrosine O-sulfate ester group in addition to the desulfonated 3’-phosphoadenosine-5’-phosphate.
TPST1 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 354 amino acids (26-370 a.a.) and having a molecular mass of 40.6kDa (Migrates at 40-57kDa on SDS-PAGE under reducing conditions).
TPST1 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
