The high mobility group proteins, HMG 14 and 17, have been associated with the chromatin of active genes (refs 18), although how they function is not known. We use sedimentation and electric dichroism to investigate the effect of HMG 14 and 17 on the condensation of chicken erythrocyte chromatin into higher order structure. We find no evidence that excess HMG 14 and 17 induce an extended configuration, either in bulk, chromatin or in the chromatin of the chicken ß-globin gene.
