We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | Human lactoferrin (hLf) has considerable potential as a therapeutic agent. Overexpression of hLf in the fungus Aspergillus awamori has resulted in the availability of very large quantities of this protein. Here, the three-dimensional structure of the recombinant hLf has been determined by X-ray crystallography at a resolution of 2.2 A. The final model, comprising 5339 protein atoms (residues 1-691, 294 solvent molecules, two Fe3+and two CO32- ions), gives an R factor of 0.181 (free R = 0.274) after refinement against 32231 reflections in the resolution range 10-2.2 A. Superposition of the recombinant hLf structure onto the native milk hLf structure shows a very high level of correspondence; the main-chain atoms for the entire polypeptide can be superimposed with an r.m.s. deviation of only 0.3 A and there are no significant differences in side-chain conformations or in the iron-binding sites. Dynamic properties, as measured by B-value distributions or iron-release kinetics, also agree closely. This shows that the structure of the protein is not affected by the mode of expression, the use of strain-improvement procedures or the changes in glycosylation due to the fungal system. | ||
