... the remaining b-strands, with the exception of strand 6, are arranged in two antiparallel beta sheets within the a-crystallin domain. The inter- face between monomers of a dimer involves interaction between ... directly in the dimer–dimer interface. As a result of the spatial dis- position of monomers and their b-strand elements in the a-crystallin domain, the am...
