INDIVIDUAL B-FACTOR REFINEMENT WAS PRECEEDED REMARK 3 BY TLS REFINEMENT IN WHICH EACH MONOMER WAS DIVIDED INTO THREE REMARK 3 TLS GROUPS. THE DEPOSITED STRUCTURE SHOWS ANISOTROPIC B REMARK 3 FACTORS THAT RESULT FROM THE COMBINATION OF THE TLS COMPONENTS REMARK 3 WITH THE RESIDUAL INDIVIDUAL B FACTORS. THE CCP4 PROGRAM REMARK 3 TLSANAL WAS USED TO COMBINE THE TWO.
