Dioxygen Binding

TNRTB Archive - Retained for reference information

Once again, elegant designs in nature challenge a naturalistic paradigm. Using extremely high resolution x-ray crystallography, a team of molecular biologists discovered an amazing design feature in an oxygen-activating metalloenzyme. They found an electrical triggering device that takes advantage of the unique properties of dioxygen. The device prevents the binding and activation of oxygen unless catalysis (stimulation of the particular chemical reaction) is primed or prepared to proceed. This molecular device limits the premature release of harmful reduced oxygen. The complexity and functionality of the device rivals the best achievements in comparable humanly-designed electronics.

In 1999, I left my position in R&D at a Fortune 500 company to join Reasons to Believe because I felt the most important thing I could do as a scientist is to communicate to skeptics and believers alike the powerful scientific evidence—evidence that is being uncovered day after day—for God’s existence and the reliability of Scripture.
