Enzymes That Destroy Blood Group Specificity
An a-L-fucosidase was purified approximately 600-fold from Clostridium perfringens; it is free of other glycosidases present in the crude extract. The fucosidase occurs in multiple “isozymic” forms with molecular weights greater than 200,000. It is an oc-(1 + 2)-specific L-fucosidase with action on oligosaccharides and glycoproteins, but with no action on simple methyl or nitrophenyl fucosides....
متن کاملA New Human Duffy Blood Group Specificity
The Duffy blood group system of human erythrocytes comprises a membrane glycoprotein recently characterized by immunoprecipitation techniques (1) . It is a polymorphic system that includes determinants for five alloantigens, two of which are Mendelian alleles (Fya and Fyb) (2, 3) . A null genotype, designated Fy(ab-) (4), lacks the expression of both Fya and Fyb, and is inherited as a third all...
متن کاملComplex glycosphingolipids with blood-group A specificity.
The oligosaccharide chains present in blood-group ABH glycoproteins and glycolipids of glandular epithelial tissue exhibit a considerable degree of heterogeneity with respect to length of carbohydrate chains and degree of branching [l-6] . The sizes of the largest blood-group-active oligosaccharide chains from horse gastric mucosa are in the range of 812 sugar residues [7] , whereas those from ...
متن کاملAntibody of blood-group specificity in simple ("cold") haemolytic anaemias.
Two cases of "cold" (simple) haemolytic anaemia are described. The serological investigation showed conclusively that the sera of both patients contained an anti-I antibody and that their cells were I positive. The antibody found is thus a true auto-antibody. This is in keeping with the findings obtained previously in the "warm" (hyperimmune) type of haemolytic anaemia.
متن کاملNon-specificity of Phage Enzymes
The phage enzymes can lyse the host in which they resides, but it is not yet known whether they show any effect on the non-susceptible hosts on solid media (Consortia). It is observed during our studies that the consortial lawn on the solid medium shows clear plaques irrespective of their specificity to the inoculated phages. The consortial studies indicate the combined application of phage enz...
