COMMENTARY hide
LITERATURE
A216G
the partially humanized mutant acquires human-like P1 Phe- and angiotensin-cleaving capacity
K192M
L40A
-
mutant enzyme retains strong preference for Phe8 with angiotensin I substrate but with Tyr4 hydrolytic rates enhance 16fold compared to wild-type enzyme
R143Q
R143Q/K192M
additional information
-
enzyme deficient animal, lack in processing of pro-matrix metalloprotease 9 to its active form and marked defect in processing of pro-matrix metalloprotease 2. Mutant animals show an increase in collagen in the ear tissue accompanied by increased ear thickness and a higher content in hydroxyproline. Lung and ear tissue of mutant animals show increased staining for fibronectin
