| 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, self-incompatibility is controlled by the single, multiallelic locus S.CATALYTIC ACTIVITY:Two-stage endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotides with 2',3'-cyclic phosphate intermediates.PTM:N-linked core structure at Asn-91, Asn-137, and Asn-153 contains xylose and at Asn-195 contains xylose and fucose.SIMILARITY:Belongs to the RNase T2 family.CAUTION:Gln-105 is present instead of the conserved Glu which is expected to act as an active site proton donor. |
