M-CSA Mechanism and Catalytic Site Atlas

Arginine kinase (M-CSA:86)

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.
