26162744 Data show the protein structure of GALE and its substrate binding and specificity. It is mutated in type III galactosemia. [review]
25201731 These data indicated a critical role of GALE in maintaining cartilage homeostasis, and suggested that GALE inhibition might contribute to OA progress.
25150110 human UDP-galactose 4'-epimerase stability is increased by variants associated with type III galactosemia but decreased by substrate and cofactor binding
23644136 GALE variants can be arranged into three groups depending on the severity of enzyme impairment.
22613355 P.K161N-hGALE causes its effects by abolishing an important interaction between the protein and the cofactor.
19250319 Our observations show that altered protein stability is due to misfolding and that loss or reduction of enzyme activity is responsible for the molecular defects underlying GALE-deficiency galactosemia.
18188677 Subtle biochemical and metabolic abnormalities detected in patients expressing these GALE alleles likely reflect, at least in part, the reduced enzymatic activity of the encoded GALE proteins.
16302980 Data suggest that reduced catalytic efficiency and increased proteolytic susceptibility of UDP-galactose 4-epimerase are causative factors in type III galactosemia.
16302980 Disease-causing mutations result in a variety of changes to the steady-state parameters. Mostly these are changes in turnover number, kcat. The ability to dimerize is not affected, but some mutants have increased sensitivity to protease digestion.
15701638 Resulst describe the relationship among UDP-galactose 4'-epimerase activity, substrate specificity, metabolic balance, and galactose sensitivity in mammalian cells.
