Crystal Structure of the Calcium-Binding Pollen Allergen Phl p 7 (Polcalcin) at 1.75 Angstroem

The structure was published by Verdino, P., Westritschnig, K., Valenta, R., and Keller, W., in 2002 in a paper entitled "The cross-reactive calcium-binding pollen allergen, Phl p 7, reveals a novel dimer assembly" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.75 Å and deposited in 2001.

The experimental data on which the structure is based was also deposited.
