Regulation
of gene expression in response to heavy metals exposure by hyperthermophilic
archaeal organisms is a major area of interest.
The outcomes of our research are expected to answer important
questions: What are the molecular mechanisms of metal metabolism,
the determinants of metal resistance and the targets of metal
toxicity in hot environment? What are and how are the pathways
of metal metabolism regulated at the genetic level? To answer
these questions we employ biochemical and molecular biology tools
in addition to microarray technology to predict functional roles
of unknown genes, characterize proteins and regulatory networks
involved in heavy metals metabolism. Sulfolobus solfataricus,
an hyperthermophilic archaeon that lives in acidic hotsprings
(pH3, 80°C), with its completely sequenced genome, is our
model system. Another area of interest is the functional genomics
analysis of Sulfolobus to discover and characterize genes with
roles in the biodegradation of chemical contaminants.
