Protein Variants

Protein Variants Comment Organism
Y228L/R283G (R)-alpha-methylbenzylamine as neutral amine is substrate of mutant Y228L/R283G, while an active-site residue, likely Tyr224, must be uncharged for productive binding. The oxidative half-reaction is unperturbed by the mutation and with flavin oxidation preceding product release Sus scrofa
