Homework Answers
Answer :- correct option is :
C) adenylosuccinate synthetase
Explanation :-
IMP is an intermediate and one branch point in purine synthesis.
IMP is irreversibly converted to AMP by two enzymatic steps.
sAMP is formed by condensation of aspartic acid and then
IMP is catalysed by adenylosuccinate synthase.
