Fig. 7. Comparison of a short sequence found in the Xcat-2
protein and selected proteins that interact with nucleic acids. A 10
amino acid stretch in Xcat-2 showed identity with 7 amino acids
(9 allowing conserved substitutions) with a region in histone H1
located within the DNA-binding loop. A search of protein
sequence banks revealed a short list of other proteins 70%
identical with this region; none were completely identical. Many
of these proteins interact with nucleic acids or nucleotides.
Selected examples of such proteins are listed. Amino acids
identical to the Xcat-2 region are boxed, conserved substitutions
are marked with a black dot. The histone H1 sequence is identical
in cow, human, rabbit, chicken, mouse and rat (Allan et al., 1980).
DpnI is a restriction enzyme, endonuclease from Streptococcus
pneumonia. Also listed are AT-BP1, a zinc finger protein found in
rats (Mitchelmore et al., 1991); EF-Tu, an elongation factor
(Jurnak, 1985); LCVLA L protein, a RNA-dependent RNA
polymerase (Singh et al., 1987); NADH dehydrogenase
(ubiquinone). Image published in: Mosquera L et al. (1993) Copyright © 1993. Image reproduced with permission of the publisher and the copyright holder. This is an Open Access article distributed under the terms of the Creative Commons Attribution License. Larger Image Printer Friendly View |
