CRYSTALLOGRAPHIC AND SOLUTION STUDIES OF N-LITHOCHOLYL INSULIN: A NEW GENERATION OF PROLONGED-ACTING INSULINS.
OverviewOverview
The addition of specific bulky hydrophobic groups to the insulin molecule, provides it with affinity for circulating serum albumin and enables it to, form soluble macromolecular complexes at the site of subcutaneous, injection, thereby securing slow absorption of the insulin analogue into, the blood stream and prolonging its half-life once there. N-Lithocholic, acid acylated insulin [Lys(B29)-lithocholyl des-(B30) human insulin] has, been crystallized and the structure determined by X-ray crystallography at, 1.6 A resolution to explore the molecular basis of its assembly. The unit, cell in the crystal consists of an insulin hexamer containing two zinc, ions, with two m-cresol molecules bound at each dimer-dimer interface, stabilizing an R(6) conformation. Six covalently bound lithocholyl ... [(full description)]
