Hyperthermophily and the origin and earliest evolution of life

Islas Graciano, Sara Ernestina; Velasco, AM; Becerra Bracho, Arturo Carlos ll; Delaye, L; Lazcano Araujo Reyes, Antonio Eusebio (2003)

The possibility of a hightemperature origin of life has gained support based on indirect evidence of a hot. early Earth and on the basal position of hyperthermophilic orizanisms in rRNAbased phylogenies. However, although ...
On the origin of metabolic pathways

Lazcano Araujo Reyes, Antonio Eusebio; Miller, SL (1999)

The heterotrophic theory of the origin of life is the only proposal available with experimental support. This comes freom the ease of prebiotic synthesis under strongly reducing conditions. The prebiotic synthesis of organic ...
Protein disulfide oxidoreductases and the evolution of thermophily: was the last common ancestor a heatloving microbe?

Becerra Bracho, Arturo Carlos ll; Delaye, L; Lazcano Araujo Reyes, Antonio Eusebio; Orgel, L (2007)

Protein disulfide oxidoreductases (PDOs) are redox enzymes that catalyze dithioldisulfide exchange reactions. Their sequences and structure reveal the presence of two thioredoxin fold units, each of which is endowed with ...
