Phylogenetic analysis of CriC. Phylogenetic analysis of CriC and Cyclic dipeptide synthase with tryptophan or alanine as a substrate. cWW, cWL, cWA, cWP, cWV refer to cyclic dipeptides formed by tryptophan with tryptophan, leucine, alanine, proline, and valine, respectively, while cAA and cAG refer to cyclic dipeptides formed by alanine with alanine and glycine, respectively. Phylogenetic trees were constructed using MEGA X the maximum likelihood method
