Purification of calf intestinal lactase

Biochimica et Biophysica Acta, 1952
Abstract A procedure for preparing a purified lactase from calf intestine is described. The enzyme preparation obtained has about 100 times the activity of the original extract, an optimum pH range of 5.5–6.0, and is maximally stable in solution at pH 5.0. Glucose inhibits hydrolytic action of the enzyme but galactose has no effect.

Midgut Lactase of the Honeybee

Journal of Apicultural Research, 1981
SummaryLactase (β-galactosidase) was found in the midguts of normal adult worker honeybees and in those fed with lactose. Sephadex G-200 chromatograms of midguts of both groups showed two enzyme activity peaks, molecular weights of lactase being determined as 238 000 and 40 000, respectively.
