A COMPARISON OF THE AMINO-TERMINAL SEQUENCES OF TWO CALF-THYMUS CHROMATIN NON-HISTONE PROTEINS

Abstract
The N-terminal sequences of 2 calf-thymus non-histone chromosomal proteins, HMG-1 and HMG-2, are compared. Both N-terminal sequences are basic and differ at only 1 position. This contrasts with the C-terminal portion of HMG-1 which was previously shown to be high in acidic residues. There is no obvious sequence homology with any of the known sequences of the histones.
