Scientists claim to have created a billion-year-old bacterial enzyme and then trace its evolution through history to the modern day.
A team at Waikato University has used new computational techniques to make accurate predictions about the size, shape and composition of proteins from ancientbacteria, ‘Journal of Molecular Biology and Evolution’ reported.
The scientists then coaxed modern bacteria into making these ancient proteins for them, creating a billion-year-old Bacillus bacteria enzyme. “We’ve been able to make a billion-year-old protein enzyme that actually works in laboratory,” said team member Jo Hobbs.
