Abstract

Two proteins, HMG-T1 and HMG-T2, with electrophoretic mobilities and compositions similar to those of protein HMG-T, were isolated from trout testes nuclei. The isoelectric points of proteins HMG-T1, HMG-T2 and HMG-T differ. The first 20 residues of protein HMG-T2 have been sequenced and differ from protein HMG-T by only one residue.
