α-d-glu·co·si·dase

(glū-kō'si-dās),
Maltase; a glucohydrolase removing terminal nonreducing 1,4-linked α-glucose residues by hydrolysis, yielding α-glucose; a deficiency of the lysosomal enzyme is associated with glycogen storage disease type II. At least five isozymes of maltase exist.
Synonym(s): glucoinvertase

maltase

/mal·tase/ (mawl´tās)
2. any enzyme with similar glycolytic activity, cleaving α-1,4 and sometimes α-1,6 linked glucose residues from nonreducing termini; in humans there are considered to be four such enzymes; two are the heat-stable enzymes, usually called maltases, constituting the glucoamylase complex; the other two are the heat-labile enzymes, usually called sucrase and isomaltase.

maltase

(môl′tās′, -tāz′)
n.
An enzyme that catalyzes the hydrolysis of maltose to glucose.

maltase

An enzyme that splits MALTOSE.

maltase

an enzyme that hydrolyses MALTOSE to glucose. In mammals it is produced in the CRYPT OF LIEBERKUHN in the SMALL INTESINE and is present in the SUCCUS ENTERICUS. Maltase is also present in many seeds.

maltase

an enzyme that hydrolyzes α-glucosides to glucose; there are two maltases found at the brush border of the intestinal epithelium, where they hydrolyze maltose (a product of the digestion of starch) to glucose for absorption. Maltase is absent from the intestine at birth and calves are unable to properly digest starch as a result.

For example, involvement of the diaphragm usually occurs late in the disease process in Duchenne muscular dystrophy (DMD) while in motor neurone disease (MND) and acid maltase deficiency, diaphragmatic weakness may be the first presentation of the disorder (10).
Pompe disease, first identified in 1932 by Dutch pathologist Johann Pompe, is a condition in which a person is born with an extreme shortage of the acid maltase enzyme.
