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.SIMILARITY:Belongs to the RNase T2 family.CAUTION:Gln-122 is present instead of the conserved Glu which is expected to act as an active site proton donor."
