Given some enzymes of ethylene biosynthetic pathway and its
character;
A) ACC
synthase i)
It is an unstable, cytosolic enzyme. Its level is regulated by environmental
and internal factors, such as wounding, drought stress, flooding, and auxin
B) ACC
oxidase ii)
It catalyzes the last step in ethylene biosynthesis, the conversion of ACC to
ethylene
iii)
Its activity can be the rate-limiting step in ethylene biosynthesis
iv)
That is encoded by a multigene family that is differentially regulated
v)
It is present in such low amounts in plant tissues and is very unstable and
also difficult to purify the enzyme for biochemical analysis
vi)
These enzymes belong to the Fe2+/ascorbate oxidase superfamily
Find out the correct combination from the given enzymes and its character?
