41. These water molecules then form hydrogen bonds to a conserved aspartate residue on the enzyme. 42. GOT2 converts oxaloacetate into aspartate by transamination. 43. They induced shedding in Xenopus laevis by adding the excitatory amino acid L-aspartate . 44. All or most aspartate peptidases are endopeptidases. 45. They are aspartate proteases, which cleave peptides with the use of a water molecule. 46. The pyrimidines are partly assembled from aspartate ( derived from " oxaloacetate " ). 47. This transfer is so that the oxaloacetate can be converted to aspartate or other amino acids. 48. The biosynthesis of aspartate is a one step reaction that is catalyzed by a single enzyme. 49. The aspartate residue stabilizes the positive charge on the nitrogen atom in the oxazolinium ion intermediate. 50. Aspartoacylase is used to metabolize N-acetyl-L-aspartate by catalyzing its deacylation.
