| Abstract | Asparaginase, which is found in various plant, animal and bacterial cells, catalyses the deamination of asparagine to yield aspartic acid and an ammonium ion, resulting in a depletion of free circulatory asparagine in plasma [ 3026924]. The enzyme is effective in the treatment of human malignant lymphomas, which have a diminished capacity to produce asparagine synthetase: in order to survive, such cells absorb asparagine from blood plasma [2407723, 3379033] - if Asn levels have been depleted by injection of asparaginase, the lymphoma cells die. Glutaminase, a similar enzyme, catalyses the deaminination of glutamine to glutamic acid and an ammonium ion [2407723]. Both enzymes are homotetramers [3026924]: two threonine residues in the N-terminal half of the proteins are involved in the catalytic activity. |

Alignments of sequences to 13 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
|
|
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
