A new variant of G6PD associated with chronic non-spherocytic haemolytic anaemia (CNSHA) in an Irish male is described. This variant is unique in that it has a normal electrophoretic mobility, Michaelis constant for G6P and NADP, and a normal pH optimum, together with a marked increase in utilisation of the substrate 2 deoxy glucose-6-phosphate. It is also relatively heat stable when compared w...

From 1981 to 1983, 15,097 X-chromosomes were genetically extracted from a number of North American populations of D. melanogaster and were electrophoretically screened for rare mobility and activity variants of glucose-6-phosphate dehydrogenase (G6PD). Overall, 13 rare variants were recovered for a frequency of about 10(-3). Eleven variants affect electrophoretic mobility and are apparently str...

The activities of glucose 6-phosphate and 6-phosphogluconate dehydrogenases, transketolase, phosphoglucose isomerase, and fructose 6-phosphate kinase were studied in extracts of wintering poplar (Populus gelrica) xylem. The xylem of wintering poplar showed high levels of transketolase, glucose 6-phosphate, and 6-phosphogluconate dehydrogenases. On recommencement of growth, the two dehydrogenase...

INTRODUCTION Nucleotide 1311 polymorphism at exon 11 of the glucose-6-phosphate dehydrogenase (G6PD) gene is fairly common in various populations worldwide, especially among Mediterranean populations. In this study, 1311 polymorphism in G6PD-deficient cases was identified by microarray technique. MATERIAL AND METHODS Four hundred and fifty clinically healthy subjects were screened and 32 case...
