| Addtional Information | FUNCTION:Self-incompatibility (SI) is the inherited ability of a flowering plant to prevent self-fertilization by discriminating between self and non-self pollen during pollination. 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.TISSUE SPECIFICITY:Pistil.SIMILARITY:Belongs to the RNase T2 family.CAUTION:Gln-112 is present instead of the conserved Glu which is expected to act as an active site proton donor. |
