Abstract
Ribosomal protein L3 is one of the proteins from the large ribosomal subunit. In Escherichia coli, L3 is known to bind to the 23S rRNA and may participate in the formation of the peptidyltransferase centre of the ribosome. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities includes bacterial, red algal, cyanelle, mammalian, yeast and Arabidopsis thaliana L3 proteins; archaeal Haloarcula marismortuiHmaL3 (HL1), and yeast mitochondrial YmL9 [ 1 , 2 , 3 ].
This entry represents a domain found in L3 proteins from archaea and eukaryotes.1. YmL9, a nucleus-encoded mitochondrial ribosomal protein of yeast, is homologous to L3 ribosomal proteins from all natural kingdoms and photosynthetic organelles. Eur. J. Biochem. 206, 373-80
