Sequence of a cDNA encoding human galactose-1-phosphate uridyl transferase.

Abstract

We report a revised sequence of a cDNA that encodes a human galactose-1-phosphate uridyl transferase. The cDNA is 1295 bases in length and encodes a 43,000 Mr protein. The sequence was derived from a cDNA clone isolated from a transformed human lymphoblast cell line and amplified in a polymerase chain reaction. The revised sequence reveals a higher degree of amino acid conservation between the human enzyme and the homologous enzymes from Escherichia coli and yeast than was previously thought to exist.
