Analysis of the regions coding for transfer RNAs in Kluyveromyces lactis mitochondrial DNA.

AUTOR(ES)
RESUMO

The major regions coding for the transfer RNA genes in the mitochondrial DNA of K. lactis were studied. Twenty one, out of a supposed twenty four tRNA genes were identified and localized with respect to other mitochondrial genes. Most of the tRNA genes were found in a cluster downstream of the large ribosomal RNA gene. The order of a few groups of genes is conserved with respect to S. cerevisiae and T. glabrata. The highly diverged intergenic sequences contained a large number of guanine-cytosine clusters which frequently formed long palindromic sequences.
