Where are you from, and what is your role in Extreme 2004?
from Taiwan, but live in New Zealand now. Job on land: Ph.D.
student of Roy Daniel and Craig Cary's at University of Waikato,
New Zealand. My project involves mostly molecular biology and
What questions are you trying to answer and why?
Trying to answer: How life adapts to extreme environments through changes
in the properties of enzymes. Enzymes are the basic compounds in cells that
catalyze all biochemical reactions, and they are very sensitive to change
in temperature, just like most other proteins. One of the organisms studied
in this cruise, the pompeii worm, is extraordinary, for the difference in
temperatures at its head and tail can be up to 80° Celsius! We'd like
to know what special properties of its enzymes enabled it to endure such
extreme conditions, and, ultimately, use the information we learned to describe
the behavior or enzymes more accurately.
