Abstract

This article describes the crystal packing of the unliganded antibody fragment from the NIST reference antibody 8671, whose atomic coordinates are available as Protein Data Bank structure 5K8A [1]. Here we give information on the crystallization and structure determination, show that the packing is unique, and describe the basis for the crystal’s twinned growth. Twinning is a common and often serious problem in protein structure determination by x-ray crystallography [2]. In this case the twinning is due to a small deviation (about 0.3 nm) from 4-fold symmetry in the primary crystal-building contact. The deviation produces pseudosymmetry, generating slightly different conformations of the protein, and alternating strong and weak forms of key packing interfaces.
