GO:0000461:   endonucleolytic cleavage to generate mature 3"-end of SSU-rRNA from (SSU-rRNA, 5.8S rRNA, LSU-rRNA)
Endonucleolytic cleavage at the 3"-end of the SSU-rRNA from an originally tricistronic rRNA transcript that contained the Small Subunit (SSU) rRNA, the 5.8S rRNA, and the Large Subunit (LSU) rRNA in that order from 5" to 3" along the primary transcript, to produce the mature end of the SSU-rRNA.
