Amino terminal sequence of the mitochondrial protein mtDBP-C: similarity with nonhistone chromosomal proteins HMG I and 2
Abstract
We have previously reported the characterization of a DNA-binding protein isolated from Xenopus !aevis mitochondfia (mtDBP-C). The amino terminal sequence of this protein (26 residues) has been determined by automated Edman degradation and used to search for sequence similarity with the NBRF library. A segment of 17 amino acids displays 47. 1% of identity with proteins HMG-1 and 2 of various vertebrate species. amino acid sequence / mitochondria / DNA-binding protein / HMG proteins
