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:The N-glycans attached at Asn-74 and Asn-77 consist of either monosaccharide (GlcNAc) or disaccharide (GlcNAc-GlcNAc) that could not be distinguished. The N-glycan at Asn-144 contains mannose and xylose, and at Asn-126 contains mannose, xylose and fucose. The N- glycan at Asn-172 consists of disaccharide (GlcNAc-GlcNAc).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."
