HUMAN SERUM TRANSFERRIN, RECOMBINANT N-TERMINAL LOBE
OverviewOverview
The N-lobe of human serum transferrin (hTF/2N) has been expressed in baby, hamster kidney cells and crystallized in both orthorhombic (P212121) and, tetragonal (P41212) space groups. Both crystal forms diffract to high, resolution (1.6 and 1.8 A, respectively) and have been solved by molecular, replacement. Subsequent refinement resulted in final models for the, structure of hTF/2N that had crystallographic R-factors of 18.1 and 19.7%, for the two crystal forms, respectively; these models represent the, highest-resolution transferrin structures determined to date. The hTF/2N, polypeptide has a folding pattern similar to those of other transferrins, including the presence of a deep cleft that contains the metal-binding, site. In contrast to other transferrins, both crystal forms of hTF/2N, ... [(full description)]
