Protein Variants | Comment | Organism |
---|---|---|
A150T | site-directed mutagenesis, the mutant shows slightly higher Vmax with olmesartan medoxomil compared to the wild-type enzyme | Homo sapiens |
Y155C | site-directed mutagenesis, the enzyme mutant is caused by a single nucleotide polymorphism rs35489000 and shows 50% reduced olmesartan medoxomil-hydrolase activity, slightly higher Km, and lower Vmax compared to the wild-type protein | Homo sapiens |

intestine | Tthe protein and activity are highly distributed in the proximal region (duodenum and jejunum) and decrease to the distal region of the intestine, high 16fold interindividual variability in both the protein and activity in the intestinal segments from the duodenum to colon. The interindividual variability in the duodenum and jejunum was relatively small, i.e. 3.0fold and 2.4fold, respectively | Homo sapiens | - |
