And Dieter Rehder's work, she knew, had been instrumental in leading her to this moment.
She had been studying the effects of cobalt(II) ions on the protein structure of a specific enzyme involved in DNA replication. Her hypothesis was that the metal ion played a crucial role in stabilizing the enzyme's active site, allowing it to function efficiently.
Also, note that, I generated this draft based on general knowledge and did not have access to Dieter Rehder's pdf. If you need specific information from the pdf you may need to verify it.
Maria's mind was racing with the implications. Could this be evidence of a more complex, even intelligent, behavior by metal ions in biological systems? She knew that Rehder's work had laid the foundation for understanding the role of metal ions in biology, but this new discovery seemed to be pushing the boundaries of what was thought possible.
