The wide expansion of hepatitis delta virus-like ribozymes throughout trypanosomatid genomes is linked to the spreading of L1 Tc / ingi clade mobile elements

Note: *means an ambiguous fitting, and ! means data probably over-estimated. In all cases, the ribozyme kinetics fitted the R² coefficient two-phase exponential decay model better than the hyperbolic model.
