Additional Information

Notes:

1.) Source organism:  Leptographium truncatum strain WIN(M)1435

2.) Host gene:  Small subunit ribosomal RNA, mitochondrial

3.) Intron-encoded

4.) Cleavage activity verified by flow cytometry via the tethered DNA cleavage assay (on the surface of yeast) and by an in vitro cleavage assay (with surface-released protein).  Orientation of target site is verified.

5.) Alternative sequence of endonuclease with mutations incorporated that are intended to increase overall solubility for in vitro studies:
