asparagine synthase (glutamine-hydrolysing) M-CSA #302 | Asparagine synthetase B catalyses the ATP dependent formation of asparagine from aspartate using either glutamine or ammonia as a nitrogen source. The enzyme is a homodimer with two active sites [PMID:10587437] in each subunit, one responsible for glutamine hydrolysis and one for asparagine synthesis, separated by a hydrophobic intramolecular tunnel around 20A long [PMID:12706338]. Sequencing analysis has shown the synthetase to belong to the larger glutamine transferase family. | Defined by 6 residues: ALA:A-1LEU:A-50ASN:A-74GLY:A-75THR:A-321ARG:A-324 | EC: 6.3.5.4 (PDB Primary Data) |
