COMMENTARY hide
LITERATURE
C524A
91.8% reduction of activity compared to wild-type enzyme. When the k136A/pYES2 and C524A/pYX243 ADC1 plasmids are coexpressed in the same yeast cells, there is about 25% functional rescue of ADC activity
K136A
97.7% reduction of activity compared to wild-type enzyme. When the k136A/pYES2 and C524A/pYX243 ADC1 plasmids are coexpressed in the same yeast cells, there is about 25% functional rescue of ADC activity
X128W
-
the purified X128W variant protein catalyzes the decarboxylation of L-arginine with a pH optimum near 3.4 with increased Km and decreased kcat values compared to the wild type enzyme
C487A
E109Q
E109Q mutation reduces the activity by 7.7fold compared to the wild type enzyme, reduced decarboxylation activity results in part from incomplete pyruvoyl-group formation
N47A
The activity of N47A is reduced by 500fold compared with the wild type protein
S53A
nonprocessing mutant enzyme
T142A
Paramecium bursaria chlorella virus
-
site-directed mutagenesis, structural comparison to the wild-type enzyme, overview
D296E
Paramecium bursaria Chlorella virus-1
-
responsible for changes in substrate specificity
E296D
Paramecium bursaria Chlorella virus-1
-
increased Km and decreased turnover with L-Arg, minor effect on Km with L-ornithine, decreased turnover with L-ornithine
