Abstract
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.
