EnGen Lba Cas12a from Lachnospiraceae bacterium ND2006 is a site-specific DNA endonuclease guided by a single 41-44 nucleotide guide RNA (gRNA) . Targeting requires a gRNA complementary to the target site as well as a 5' TTTV protospacer adjacent motif (PAM) on the DNA strand opposite the target sequence. Cleavage by EnGen Lba Cas12a occurs ~18 bases 3' of the PAM and leaves 5' overhanging ends. EnGen Lba Cas12a has Simian virus 40 (SV40) T antigen nuclear localization sequences (NLS) at both the N and C-termini of the protein.
