Evolution of tuf genes: ancient duplication, differential loss and gene conversion.

abstract：:Antibodies generated against synthetic peptides that correspond to highly conserved sequence motifs in the annexins reacted with a variety of annexins from different species. These include Xenopus laevis and Drosophila melanogaster, which contain cross-reacting polypeptides of apparent Mr 34,000 and 30,000. As expecte...
