Expression and cellular localization of Trypanosoma cruzi type II DNA topoisomerase.

abstract：:We report the isolation and sequence of a part of a gene encoding a collagen from the genome of the human filarial parasite Brugia malayi. The deduced amino acid sequence of the sequenced portion of this gene, which we have designated BmCol1, differs from the most catalogued nematode collagens in that it is composed p...
