Putative high mobility group (HMG) non-histone chromosomal proteins from wheat germ. Isolation, characterisation and partial sequence analysis

Abstract

Four proteins have been isolated from wheat germ by methods analogous to those used to isolate HMG proteins from animal tissue. All four proteins have been shown to be chromosomal in origin. Although amino acid analyses show that three of these proteins have compositions similar to those of the mammalian HMG proteins, N-terminal sequence analyses of these proteins show an absence of sequence homology with any of the mammalian HMG proteins.
