DELTAS308-K321 | deletion of 14 amino acids from Ser308 to Lys321 in a surface loop (connecting beta-strands 12 and 13) transforms the enzyme from a dimeric protein into a stable monomer. The mutant enzyme is still catalytically competent and retains its binding with the FAD coenzyme. The Kd value of the apoprotein-FAD complex is 5fold higher than that of the wild-type enzyme. 1.9fold increase in Km-value for D-Ala, 1.8fold decrease in Vmax value with D-Trp | Rhodotorula toruloides |

incubation of the mutant enzyme DELTASer308-Lys321 with 10% trypsin in presence of exogenous FAD, 0.2 mM, shows that the rate of activity loss is lower than that determined in absence of exogenous FAD | Rhodotorula toruloides |
