Attempts have been made to model the tertiary structure of other group II introns, such as the ai5γ group IIB intron, using a combination of programs for homology mapping onto known structures and de novo modeling of previously unresolved regions. Group IIC are characterized by a catalytic triad made up by CGC, while Group IIA and Group IIB are made up by AGC catalytic triad, which is more similar to the catalytic triad of the spliceosome.
Various efforts have been made to simulate the tertiary structure of other group II introns, including the ai5γ group IIB intron. These models use a combination of homology mapping onto known structures and de novo modeling for unresolved regions. Group IIC are characterized by a catalytic triad composed of CGC, while Group IIA and Group IIB have an AGC catalytic triad, which is more similar to the catalytic triad in the spliceosome.
