Objective(s): To gain an understanding of how the diversity and evolution of microbial metallo-enzymes was influenced by the chemical composition of Archean-aged oceans through the trace metal composition of Archean-aged Banded Iron Formations.
Project Description: In the effort to better understand the early evolution of life on Earth, the research goal is to investigating how the diversity and evolution of microbial metallo-enzymes were influenced by the chemical composition of Archean-aged oceans through the trace metal composition of Archean-aged Banded Iron Formations (BIF). The data collected from samples gathered during fieldwork in the NWT will help in determining whether the trace metals available to microbes in the early Archean ocean are still used in the metallo-enzymes of modern microbes. The researcher will appraise the metal contents in some modern metallo-enzymes with advanced mass spectrometry techniques for protein identification and sequencing, in collaboration with researchers at Woods Hole Oceanographic Institute. By comparing these results with the availability of trace metals in the Archean ocean, metabolic types available to microbes at that time in Earth... Show more
