Interallelic complementation in hybrid cells derived from human diploid strains deficient in galactose-1-phosphate uridyl transferase activity. 1970

H L Nadler, and C M Chacko, and M Rachmeler

Galactose-1-phosphate uridyl transferase activity has been demonstrated in hybrid cells formed from the fusion of human diploid fibroblasts obtained from different patients with galactosemia. The enzyme produced by the hybrid cells was similar to the normal enzyme in regard to K(m), pH optimum, and electrophoretic mobility on starch gel, but differed in specific activity, V(max) and thermal stability. This is the first reported example of interallelic complementation in fused human diploid cells.

UI	MeSH Term	Description	Entries
D009713	Nucleotidyltransferases	A class of enzymes that transfers nucleotidyl residues. EC 2.7.7.	Nucleotidyltransferase
D002459	Cell Fusion	Fusion of somatic cells in vitro or in vivo, which results in somatic cell hybridization.	Cell Fusions,Fusion, Cell,Fusions, Cell
D004586	Electrophoresis	An electrochemical process in which macromolecules or colloidal particles with a net electric charge migrate in a solution under the influence of an electric current.	Electrophoreses
D005693	Galactosemias	A group of inherited enzyme deficiencies which feature elevations of GALACTOSE in the blood. This condition may be associated with deficiencies of GALACTOKINASE; UDPGLUCOSE-HEXOSE-1-PHOSPHATE URIDYLYLTRANSFERASE; or UDPGLUCOSE 4-EPIMERASE. The classic form is caused by UDPglucose-Hexose-1-Phosphate Uridylyltransferase deficiency, and presents in infancy with FAILURE TO THRIVE; VOMITING; and INTRACRANIAL HYPERTENSION. Affected individuals also may develop MENTAL RETARDATION; JAUNDICE; hepatosplenomegaly; ovarian failure (PRIMARY OVARIAN INSUFFICIENCY); and cataracts.
