abstract：:An erythroid-specific enhancer was previously identified in the 3'-flanking region of the beta adult gene in chicken and duck, by transfection into AEV transformed chicken erythroblasts. Here we show that the duck enhancer is equally active in erythroid human K562 cells, presenting an embryonic/fetal program of globin...

abstract：:Treatment of yeast phosphoglycerate kinase (PGK) with trypsin results in a fourfold increase in the Vmax of this enzyme, without affecting the Km. This activation is shown to be due to the removal of the C-terminal lysine residue. The C-terminal sequence folds back over the N-terminal domain and contacts the extreme N...
