sl4 is a CAG to TAG change in the codon for aa#1194 (Q to STOP) sl5 is a deletion of the sequence "TGATAGCCGCACGTC", this results in the deletion of the amino acids "LIAAR", aa#1115-1119. The remaining C in the codon for aa#1115 is fused to the remaining AT of codon \#1120, thus retaining the His encoded by codon \#1120. sl6 is a CAG to TAG change in the codon for aa#713 (Q to STOP) sl9 is a TGG to TAG change in the codon for aa#54 (W to STOP) sl10 is a CAG to TAG change in the codon for aa#791 (Q to STOP)
