ISOLATION AND CHARACTERIZATION OF A GENE FROM TRYPANOSOMA-CRUZI ENCODING A 46-KILODALTON PROTEIN WITH HOMOLOGY TO HUMAN AND RAT TYROSINE AMINOTRANSFERASE
Ej. Bontempi et al., ISOLATION AND CHARACTERIZATION OF A GENE FROM TRYPANOSOMA-CRUZI ENCODING A 46-KILODALTON PROTEIN WITH HOMOLOGY TO HUMAN AND RAT TYROSINE AMINOTRANSFERASE, Molecular and biochemical parasitology, 59(2), 1993, pp. 253-262
The complete sequence of a gene encoding a 46-kDa protein of Trypanoso
ma cruzi is presented. The first ATG complies with the consensus seque
nce for initiation of translation. A single band of 2 kb was highlight
ed by hybridizing a pro the 46-kDa protein gene to a Northern filter c
ontaining total T. cruzi RNA. The gene is present in 50-80 copies per
cell and most of them are contained in 2 tandem arrays on large T. cru
zi chromosomes ( > 2000 kb). A strong homology with rat and human tyro
sine aminotransferase was detected. Homology with a Trypanosoma brucei
retrotransposon was found in the nonsense strand of the intergenic re
gion.
