a MAOB mutant |
702228 |
1.4.3.4 | I199A |
mutant of MAO-B, shows reduced inhibition by (E)-5-styrylisatin and (E)-6-styrylisatin compared to wild-type MAO-B |
702565 |
1.4.3.4 | I199A |
the mutant exhibits catalytic properties with 4fold increased amine Km but unaltered kcat values |
724966 |
1.4.3.4 | I199A/Y326A |
the mutant exhibits catalytic properties with 75fold increased amine Km but unaltered kcat values. The mutant shows inhibitor binding properties more similar to those of isoform MAO A than to isoform MAO B. Benzylamine is a poor substrate for the double mutant |
