Due to their high hydrophobicity, it is a challenge to obtain high yields of transmembrane peptides for structural and functional characterization. In the present work, a robust method is developed for the expression, purification and reconstitution of transmembrane peptides, especially for those containing conserved methionines. By using a truncated and mutated glutathione-S-transferase construct...
Type 2 diabetes mellitus is characterized by impaired glucose uptake. With a photometric method of recording the erythrocyte suspension absorption during the course of glucose transport across the membranes, we observed that the initial rate of glucose zero-trans entry was decreased significantly in 30 Chinese type 2 diabetic patients as compared to 25 healthy controls. The rate of glucose infinite-cis...
