Preliminary crystallographic data on the human λIII Bence Jones protein dimer Cle

A complete human λ Bence Jones protein dimer (Cle) has been isolated and crystallized. Protein Cle was characterized immunochemically and chemically as having a variable region amino acid sequence associated with light chains of the λ chain subgroup, λIII, and a constant region sequence characteristic of “non-Mcg” type λ chains. Bence Jones protein Cle contains two covalently bound intact monomers, each having a molecular weight of ~23,000....
