Precorrin-8X methylmutase (M-CSA:193)
Proteins that are close homologues to the M-CSA reference protein and have the same catalytic residues (highlighted in green, below) probably share the same mechanism. Please also check if the homologue shares the same FunTree Structural Cluster and the same Pfam family, as another measure of similarity.
PDB sequences identical to 1f2v
In these PDB chains all the catalytic residues are conserved and have the same numbering as the reference.1i1h(A)
