It is formed by 6-phosphogluconolactonase, and acted upon by phosphogluconate dehydrogenase to produce ribulose 5-phosphate.
12.
The last step of the oxidative reactions in the pentose phosphate pathway is the production of ribulose 5-phosphate.
13.
Depending on the body's state, ribulose 5-phosphate can reversibly isomerize to ribose 5-phosphate.
14.
It interacts with both the large and small subunits of the ribulose-1, 5-bisphosphate carboxylase / oxygenase.
15.
It is C3 of D-ribulose 5-phosphate which undergoes this epimerization, forming D-xylulose 5-phosphate.
16.
There are three phases : carbon fixation, reduction reactions, and ribulose 1, 5-bisphosphate ( RuBP ) regeneration.
17.
Carbon dioxide combines with ribulose bisphosphate and proceeds to the Calvin Cycle . 4 ) Pyruvate re-enters the mesophyll cell.
18.
This epimerase participates in the third phase of the Calvin cycle, which involves the regeneration of ribulose 1, 5-bisphosphate.
19.
In addition, the Structural Classification of Proteins database has defined the ribulose phosphate binding superfamily for which this epimerase is a member.
20.
As the enzyme converts ribulose 5-phosphate into xylulose 5-phosphate, the latter is further metabolized into erythrose 4-phosphate.
