This alphabet has 20 letters, and therefore integrates well with existing tree inference software (to which a 3di alignment looks like a regular old protein alignment). This means we can use this to infer trees.

6/10 dCas12f-Sigma factors are able to recruit their native RNA polymerase (RNAP) to drive RNA-guided transcription at programmable sites. Remarkably, we were able to generate RNA (see RNA-seq) without relying on promoters in intergenic sequences, even within genes, and on either DNA strand.
