Introduction

Asparagine Synthetase (ASNS) is an enzyme that catalyzes the conversion of Aspartic Acid to Asparagine through an ATP dependent amination reaction. ASNS can be found in both plants and mammals, however, in plants there are two forms ASNS-A and ASNS-B. Both forms use the same starting molecule of Aspartic Acid and produce Asparagine, the only difference coming from the source of the Nitrogen. ASNS-A uses inorganic Nitrogen in the form of N2 and ASNS-B uses Glutamine as its Nitrogen source; ASNS-B will be the focus of this page because it is very similar and undergoes the same reaction as ASNS in mammals.

Figure.... Proposed reaction mechanism for ASNS using Aspartic Acid, Glutamine and ATP to synthesize Asparagine and Glutamic Acid.

Asparagine Synthetase catalyzes the interconversion of Aspartic Acid and Glutamine to Asparagine and Glutamic Acid. This is not a straight forward transferase reaction since the interconversion is not directly between Aspartic Acid and Glutamine. Instead this reaction more closely resembles a two part ATP dependent ligase reaction.
