Glutaminase-asparaginase catalyses the hydrolysis of D and L isomers of glutamine and asparagine.
Glutaminase-asparaginase belongs to a family of related amidohydrolases, in a less specific class that catalyses the hydrolysis of glutamine to glutamic acid and asparagine to aspartic acid with similar efficiency. They are mechanistically similar to trypsin.
