Rationally-designed meganuclease variants of lig-34 and I-crei for maize genome engineering
The invention relates to the field of molecular biology and recombinant nucleic acid technology. In particular, the invention relates to a rationally-designed, non-naturally-occurring meganuclease with altered DNA recognition sequence specificity which recognizes and cleaves a unique DNA site in the maize genome. Disclosed herein are meganucleases which are variants of the I-CreI and LIG- 34 meganucleases. The invention also relates to methods of producing engineered maize plants using such meganucleases.
1. A rationally-designed meganuclease having the amino acid sequence of SEQ ID NO: 1.
2. A rationally-designed meganuclease having the amino acid sequence of SEQ ID NO: 12.
3. A rationally-designed meganuclease having the amino acid sequence of SEQ ID NO: 13.
