In this paper, a cDNA homologous to the mammalian ribosomal protein (r-protein) L34 was isolated from a Xenopus laevis oocytes library and named XL34. It encodes a protein of 116 residues with an Mr of 13.2 kDa and a highly basic sequence. The nucleotide (nt) and deduced amino acid (aa) sequence have been compared with the L34 sequence from other species. This analysis showed that the L34 is a protein...
Previous work on the evolution of the phosphofructokinase (PFK) has shown that this key regulatory enzyme of glycolysis has undergone an intricate evolutionary history. Here, we have used a comprehensive data set to address the taxonomic distribution of the different types of PFK (ATP-dependent and PPi-dependent ones) and to estimate the frequency of horizontal gene transfer (HGT) events. Numerous...
Ameloblastin (AMBN) is an enamel sheath protein that presumably has a role in determining the prismatic structure of growing enamel crystals. To investigate the relationship between the molecular evolution of the AMBN gene and development of enamel prismatic structures, it is considered to be of great significance in the identification of homologues of the AMBN genes in nonmammals whose teeth lack...
