Rat alpha-lactalbumin is unique in contrast to alpha-lactalbumin isolated from other species in that it exists in three charge forms. Each form contains carbohydrate and is active in the lactose synthetase reaction. Form II comprises about 80% of the

Three charge forms of rat alpha-lactalbumin were separated by ion exchange chromatography on DEAE-cellulose. The amino acid composition of each form was similar but they differed in carbohydrate composition. Each form contained a tryptic glycopeptide

Galactosyltransferase exhibited a time-dependent loss of activity when incubated with sulfhydryl reagents p-chloromercuribenzoate and N-ethylmaleimide. Though incubations were continued for periods 20-fold greater than the half-time of inactivation,

Summary Previous studies (1) have reported that folic acid increases the activity of several glycosyltransferases, including a galactosyltransferase of rat liver and kidney suggesting that folic acid may be involved in the control of glycoprotein bio

The subcellular distribution of the A and B proteins of lactose synthetase (EC 2.4.1.c) has been determined in bovine and rat mammary tissue. The A protein is mainly associated with the microsomal fraction, whereas the B protein is distributed betwee

The biological role of α -lactalbumin has been elucidated recently. It is one of two proteins required for the lactose synthetase enzyme, the enzyme responsible for the biosynthesis of lactose. This enzyme requires an A protein, a B protein ( α -la

Summary Milk has received attention as a source of strontium-90 (Sr-90), since it is the major source of calcium and, hence, Sr-90, in the diet of most Western countries. Although several biologically active radioactive isotopes are produced in a ura

Galactosyl transferase activity was found in a variety of sources including rat and chicken tissues, bovine thyroid particles, rabbit gastric mucosa, L cell membranes, opossum, guinea pig, bat and hamster mammary glands and milk from the bat and hors
