CHARACTERIZATION AND COMPLETE NUCLEOTIDE-SEQUENCE OF A 5.8S RIBOSOMAL-RNA GENE FROM PLASMODIUM-FALCIPARUM

The 5.8S and 5S rRNA components from the FCR-3/The Gambia strain of Plasmodium falciparum have been identified and the complete nucleotide sequence of a 5.8S ribosomal RNA gene determined. Unlike the 5S rRNA species, the 5.8S is a single homogeneous population of molecules of 157 nucleotides. Comparison of its nucleotide sequence with previously reported 5.8S rRNA sequences indicates that it is homologous to these molecules, but distantly related to them. The sequence of the 5.8S rRNA coding region from the pfrib-2 recombinant of the HG13 Gambian isolate of P. falciparum is identical.
