Última Purine and pyrimidine nucleotide metabolism in Mollicutes Genet. Mol. Biol. Bizarro,Cristiano Valim; Schuck,Desirée Cigaran. Several mollicute genome projects are underway, offering unique opportunities to study genes and metabolic pathways on a genome-wide scale. Here, we have analyzed the conservation and diversity of purine and pyrimidine metabolism in mycoplasmas. An evaluation of discrepancies between genomic analysis and enzymatic data revealed interesting aspects about these organisms. We found important examples in which enzyme activity was reported without the annotation of a corresponding gene. An interesting example concerns phosphopentomutase. In Mollicutes, we have identified CDSs orthologous to sequences recently identified as new phosphopentomutases in archaeobacteria that are structurally related to phosphomannomutases. It is suggested that these sequences could... Tipo: Info:eu-repo/semantics/article Palavras-chave: Mollicutes; Purine; Pyrimidine; Metabolism; Metabolic pathways.

Mol. Biol. Sperb,Fernanda; Schuck,Desirée Cigaran; Rodrigues,Jaqueline Josi Samá. Transposable elements are DNA sequences present in all the large phylogenetic groups, both capable of changing position within the genome and constituting a significant part of eukaryotic genomes. The mariner family of transposons is one of the few which occurs in a wide variety of taxonomic groups, including freshwater planarians. Nevertheless, so far only five planarian species have been reported to carry mariner-like elements (MLEs), although several different species have been investigated. Regarding the number of copies of MLEs, Girardia tigrina is the only planarian species in which this has been evaluated, with an estimation of 8,000 copies of the element per haploid genome. Preliminary results obtained in our laboratory demonstrated that MLE is... Tipo: Info:eu-repo/semantics/article Palavras-chave: Mariner; Planarian; Transposable element; Transposons.
