In many species of the Solanaceae, self-incompatibility is controlled by the single, multiallelic locus S. This stylar glycoprotein is associated with expression of self-incompatibility in potato.CATALYTIC ACTIVITY:Two-stage endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotides with 2',3'-cyclic phosphate intermediates.SIMILARITY:Belongs to the RNase T2 family."
