Abstact

The tertiary structure of the macrophage migration inhibitory factor (MIF) from rat liver (12,300 Mr) is presented at 2.2 A resolution. Each monomer consists of two beta/alpha/beta motifs aligned in quasi two-fold symmetry, comprising a domain consisting of a four-stranded mixed beta-sheet and two antiparallel alpha-helices. The protein exists as a trimer in the crystal. An extra beta-strand that is almost perpendicular to the other beta-strands joins to the beta-sheet of the neighbouring monomer in the trimer. Unexpected similarities were detected between MIF and two kinds of isomerase.
