Chains	Enzyme Name	Description	Catalytic Residues
A	adenylosuccinate synthase M-CSA #65	Adenylosuccinate synthetase is an essential enzyme in Escherichia coli and many other forms of life, catalysing the first committed step in de novo biosyntheses of AMP: The catalytic mechanism proceeds with the initial formation of 6-phosphoryl-IMP by nucleophilic attack of the 6-oxo group of IMP on the gamma-phosphorus atom of GTP, followed by the nucleophilic displacement of the 6-phosphoryl group by L -aspartate to form adenylosuccinate.
